Vedas Alone Not Hinduism Shad Darsana Six Systems Indian Philosophy


Indian philosophy and the Religion of the Hindus differ from other religions in that,

1. It has no founder.

2. It is not dogmatic and one can follow what one is inclined to.

3. It has no strict rules to follow in that it does not condemn you to Hell.

4. It does not proselytize.

Brahman, The Reality

5. No single individual is considered as the authority in matters relating Hinduism

6. It has no written texts and these have been transmitted orally for over five thousand years.

7.It accommodates all views including the Atheists; you can be an Atheist and still be A Hindu.

8.It fixes individual responsibility. You can not escape from the results of your actions by assigning it to some one else.

9. It treats all Beings and also the Insentient equally.

10. There is no procedure to become a Hindu nor is there any question of expelling some one from Hinduism and readmitting.

11. Indian philosophy is based on Intuition and experience , though Logic and other tools of knowledge are used to verify or support Knowledge gained by Intuition.

The systems of Indian philosophy have the following components.

a) Theory of Knowledge or Epistemology.

The systems decide first what knowledge is and proceed what instruments to use to gain Knowledge.

There are some instruments of Knowledge through which we gain knowledge.

Knowledge is taken at its core meaning, to be aware of.

That it is correct, incorrect, Right or Wrong comes later when judgement are made.

Facts are differentiated from Impression of Facts.

Prathyaksha. Is what is known through senses.

b)Anumana is Inference.

c)Upamana is Comparison , with similar things.

d) Tharka ,  Logic where Knowledge is derived from Logical steps through Syllogism.

e) Sabda , from Testimony fro others.

f) Intuition.

The tools of knowledge followed by a system decides its philosophy..

Systems of Indian Philosophy, Religion.

In India Religion and Philosophy are interwoven.

There is no separation of the two.

A philosophy not worth practicing is not considered at all.

Religion is to be experienced and there is no such thing as Practising Religion and non practicing religion.

Many believe, even Hindus, that the Vedas alone constitute Indian Philosophy.

Not true.

We have Jainism, Buddhism, Buddhism , Carvakas and Ajivakas whih form a parf Indian Philosophy.

They existed along with the Vedas.

And they were accepted.

Another feature of Hinduism is the definition of Atheism.

It has nothing to do with the belief in God.

One can be a Hindu and remain an Atheist ,like Carvakas, Buddhist,Ajivaka.

These are totally opposed to Vedas and deny their authority.

Orthodox systems are those which belive in the Authoroty of the Vedas.

Those, like Jainism are called Heterodox and they do not believe in the Vedas.

Even among the Orthodox systems which believe in the authority of the Vedas deny God, like The Nyaya System.

Philosophical systems are called Darsana.

Darśana, also darśana or darshanam, Sanskrit: दर्शन from dṛś, meaning “to see”, vision, apparition, or glimpse.

Though there are other meanings like The darsana of God/Holy men , in Indian Philosophy the term Darsana is used in the meaning meaning provided above.

It may be called as Perspective.

Reality or Truth has many facets.

One discerns what one is inclined to

The six systems of Hinduism are.

They are called the Shad (six) Darsana

Nyaya,the realism school emphasizing analytics and logic,

Vaiseshika,the naturalism school with atomistic themes and related to the Nyaya schoo

Sankhya, the rationalism school with dualism and atheistic themes,

Yoga,school similar to Samkhya but accepts personally defined theistic themes,

Purva Mimamsa or  Mimamsa), the ritualism school with Vedic exegesis and philology emphasis

Uttara Mimasa or Vedanta, the Upanishadic tradition, with many sub-schools ranging from dualism to non-dualism.

It has nothing to do with the belief in God.

One can be a Hindu and remain an Atheist ,like Carvakas, Buddhist,Ajivaka.

These are totally opposed to Vedas and deny their authority.

Orthodox systems are those which believe in the Authority of the Vedas.

Those, like Jainism are called Heterodox and they do not believe in the Vedas.

Even among the Orthodox systems which believe in the authority of the Vedas deny God, like The Nyaya System.

Stotra Mantra Parayana Differnce


Unlike other Religions,Hinduism has Prayers of different types.

There are three different types in terms of how these were arrived at, whom they are addressed to and the results sought for.

Before understanding the differences , one must know that in Hinduism, as its fundamental Truth as enunciated in the Vedas, the Sacred texts of the Hindus,describes the Reality, called Brahman, is distinct from Brahma, The God of Creation,is Without Name and Form.

The Brahman is with out Attributes, with Attributes and beyond Attributes,

It is to be experienced and is Beyond space,time,senses,mind and time.

It is Being, Consciousness and Bliss, Sat, Chit and Ananda.

The purpose of Life is to realize the Brahman, The Reality behind the noumenon, the world of Names and Forms, the substratum of the Universe, both Macro and Micro.

To achieve this, the impediment called Mind is to be Stilled.

The cessation of the Modification of Chitta is Yoga or Union with the Reality.

Ganesa Lakshmi Stotram.jpg

( Chitta is a Higher plane of Cognition, please read my posts on Yoga, Chitta)

To Still the Mind, the thoughts or the thought waves are to be stopped.

Rama, Hanuman. SundaraKanda Parayana.Jpg

Rama, Hanuman. SundaraKanda Parayana.

But as The Mind, by its nature, is always after a thousand thoughts, it is difficult to control it,

However it can be done by Right Determination,Knowledge and Practice, says Krishna in the Bhagavad Gita( Gnana and Vairaagya)

So in the process of quieting and making the Mind still, Hinduism advocates Worship of Gods with Forms, though in Reality they do not exist.

However as Krishna says , even these Gods of Names and forms are relatively Real in the sense that they grant the boons one wishes for and Krishna says He assumes the Forms and Names Of Gods and Goddesses addressed by the practitioner and deliver the results.

So Gods of Hinduism are Real and not Real at the same time.

For details read my post ‘Hinduism, Gods with Name and Form ,Yes Or No’.

As Human dispositions and needs are varied,, so are the Gods.

One may like Mother, Father, Friend , Lover, son, daughter…

To establish a relationship, each needs a unique approach and there can be no uniform and a single window approach.

So the Gods vary and your modes of address vary.

One does not address Mother as he would his Father, Lover or Friend.

So the prayers vary.

Generally there are three types of Prayers.

Avalokeswara Mantra.png

Avalokeswara Mantra.

1.Stotra/Stuthi.

2.Parayana and

3.Mantras.

Stotras.

Stotra is from the root Stuthi, meaning ‘Praise’

If one were to get some thing from some one superior in Station, one praises him or her to get the things done for one who wishes for.

So in a Stotra one finds Praises of Gods, extolling their virtues, then requesting them to grant one’s Wishes.

We have a large collection of these Stotras.

These Stotras are also of different kinds.

One is by Gods themselves addressing the other Gods, like Krishna’s Siva Stuthi or Rudra’s Mantra Rajapadham addressed to Lord Narasimha, Indra’s Krishna Stuthi.

These are addreed to Gods whom one likes.

Another type is by the Great Rishis , like Hayagreeva’s Lalitha Sahasranama.

Yet another type is by great personalities like Bhishma, The Vishnu Sahasranama; the various slokas of Adi Shankaracharya, Swami Desikan,Ramanujacharya, Madhwacharya….

All these deliver results in terms of efficacy in the descending order described

Some of these Rishis have Prayers to a Particular Deity.

In this case it is not necessary that the God one choses to worship need be what one likes.

These Gods produce results because of the fact that the Hymn is composed by a realized Soul.

2.Parayana.

A Stuthi or a Stotra by a Great Rishi like  Valmiki, The Sundara Kanda of Ramayana is recited in a prescribed format for a fixed duration is called Parayana.

People also do this regularly as they do Lalitha Sahasra nama and Visnu Sahasranama.

The Parayana prayers may be from any of Language.

The basic requirement is Faith.

3.Mantra is different as they are locked Sounds . grasped by the Rishis, in a mysterious way.

Mantras, are the essence of Sound and Sound in its pure form is Mantra.

Mantras control Sound.

The difference between Mantras and the other two Types is that Mantras deliver guaranteed results, if one follows the procedures laid down.

Whereas in the case of Stotra or Parayana,the Divine intervention is left to  the pleasure of the God addressed to, in the case of Mantras, the Gods are obliged to grant the requests as they represent the essence of Reality and in fact the Form of Gods themselves.

That is why even A Raskshasa can deliver a Brahmastra by invoking a Mantra.

Mantras can be addressed to specific Gods and also to Reality in its Attributeless Form.

Or the Mantra can be a combination of sounds mystically locked.

Worse still is that some make funny remarks.

One of the readers in a Facebook community commented  for the Post Shankaracharya Intellectual Giant,where I listed the  His works as follows,

‘So, He could have invented sanitary Napkins!’

Death and afterWhat happens after Death..Image,jpg

Near Death NDE OBE Real Case Proves Indian Death Ceremony


People are scared of Death.

Nobody is an exception to this.

I have remarked in an article that there are two reasons for this.

One is the fear of Pain accompanying Death and another is,

The uncertainty of what would happen after death.

Would we suffer unbearable pain after Death as described in various legends and Religious Text?

What would happen to us after Death?

Are we reborn?

In that case will we be a Human being?

Will what is called as Sins haunt us?

Scroll down for video.

Indian philosophy answers this on two levels.

One is after death it is observed in Higher Philosophy,that one does not die as the Atman, the soul is eternal and is never affected by pain or births or deaths.

Another view is that, as detailed in Garuda Purana , one is made to go through various punishments for sins and granted heaven for Righteous deeds.

I tend to agree with the former explanation of soul not being touched death as death is only a transition, as Krishna puts it ,”As Human body goes through childhood, youth and old age,

Kaumaaram Yavvanam Jara’ Bhagavad Gita Chapter 2.

But one can never be sure for none is here to report these experiences.

But there are medically recorded experiences of people who have touched the jaws of Death and there are people who have out-of-body experiences.

The former is called Near Death Experience(NDE), the latter,out-of-body experience (OBE)

I have posted a couple of articles on this.

Enveloped in A Pool of Light, Near Death Experience.image.jpg Enveloped in A Pool of Light, Near Death Experience(NDE)

Now there is case well documented where the NDE is explained vividly and he medical team has recorded it with instruments.

In all these case, the philosophical view of Hinduism is reinforced.

People have reported being enveloped in a sheet of white light which felt warm, they have been able to see what is taking place, though they could not perceive, see or hear it with their senses.

The perception has become more acute.

In some cases they have been able to see their ancestors.

The ceremonies conducted by the Hindus state that after death, for twelve days the sukshma sarrera remains near the place of death, can perceive every thing and they leave only after Sabindikarana.on the twelfth day.

And Indian thought says it is Light which is the expression of Life.

The Santhi Mantra says TamasoMaa Jyotir Gamaya, Lead me from Darkness to Light.

Curious to note here is that Living is called Darkness and moving out of the body is Light!

Look at the explanation in the image below of Thirumoolar , A Siddha,in Thirumandiram is Tamil.

Samkhyas and Vedic Thoughts differ only on minor points.

Thirumoolar Explanation of Evolution of Universe.Image,Gif Thirumoolar Explanation of Evolution of Universe.

Now read the report of verified  Near Death Experience.

The report.

Pam Reynolds reports NDE.Image.jpg Pam Reynolds who had a Near Death Experience.

In 1991, Atlanta-based singer and songwriter Pam Reynolds felt extremely dizzy, lost her ability to speak, and had difficulty moving her body. A CAT scan showed that she had a giant artery aneurysm—a grossly swollen blood vessel in the wall of her basilar artery, close to the brain stem. If it burst, which could happen at any moment, it would kill her. But the standard surgery to drain and repair it might kill her too.

With no other options, Pam turned to a last, desperate measure offered by neurosurgeon Robert Spetzler at the Barrow Neurological Institute in Phoenix, Arizona. Dr. Spetzler was a specialist and pioneer in hypothermic cardiac arrest—a daring surgical procedure nicknamed “Operation Standstill.” Spetzler would bring Pam’s body down to a temperature so low that she was essentially dead. Her brain would not function, but it would be able to survive longer without oxygen at this temperature. The low temperature would also soften the swollen blood vessels, allowing them to be operated on with less risk of bursting. When the procedure was complete, the surgical team would bring her back to a normal temperature before irreversible damage set in.

Essentially, Pam agreed to die in order to save her life—and in the process had what is perhaps the most famous case of independent corroboration of out of body experience (OBE) perceptions on record. This case is especially important because cardiologist Michael Sabom was able to obtain verification from medical personnel regarding crucial details of the surgical intervention that Pam reported. Here’s what happened.

Pam was brought into the operating room at 7:15 a.m., she was given general anesthesia, and she quickly lost conscious awareness. At this point, Spetzler and his team of more than 20 physicians, nurses, and technicians went to work. They lubricated Pam’s eyes to prevent drying, and taped them shut. They attached EEG electrodes to monitor the electrical activity of her cerebral cortex. They inserted small, molded speakers into her ears and secured them with gauze and tape. The speakers would emit repeated 100-decibel clicks—approximately the noise produced by a speeding express train—eliminating outside sounds and measuring the activity of her brainstem.

At 8:40 a.m., the tray of surgical instruments was uncovered, and Robert Spetzler began cutting through Pam’s skull with a special surgical saw that produced a noise similar to a dental drill. At this moment, Pam later said, she felt herself “pop” out of her body and hover above it, watching as doctors worked on her body.

Although she no longer had use of her eyes and ears, she described her observations in terms of her senses and perceptions. “I thought the way they had my head shaved was very peculiar,” she said. “I expected them to take all of the hair, but they did not.” She also described the Midas Rex bone saw (“The saw thing that I hated the sound of looked like an electric toothbrush and it had a dent in it … ”) and the dental-drill sound it made with considerable accuracy.

Meanwhile, Spetzler was removing the outermost membrane of Pamela’s brain, cutting it open with scissors. At about the same time, a female cardiac surgeon was attempting to locate the femoral artery in Pam’s right groin. Remarkably, Pam later claimed to remember a female voice saying, “We have a problem. Her arteries are too small.” And then a male voice: “Try the other side.” Medical records confirm this conversation, yet Pam could not have heard them.

The cardiac surgeon was right—Pam’s blood vessels were indeed too small to accept the abundant blood flow requested by the cardiopulmonary bypass machine, so at 10:50 a.m., a tube was inserted into Pam’s left femoral artery and connected to the cardiopulmonary bypass machine. The warm blood circulated from the artery into the cylinders of the bypass machine, where it was cooled down before being returned to her body. Her body temperature began to fall, and at 11:05 a.m. Pam’s heart stopped. Her EEG brain waves flattened into total silence. A few minutes later, her brain stem became totally unresponsive, and her body temperature fell to a sepulchral 60 degrees Fahrenheit. At 11:25 a.m., the team tilted up the head of the operating table, turned off the bypass machine, and drained the blood from her body. Pamela Reynolds was clinically dead.

At this point, Pam’s out-of-body adventure transformed into a near-death experience (NDE): She recalls floating out of the operating room and traveling down a tunnel with a light. She saw deceased relatives and friends, including her long-dead grandmother, waiting at the end of this tunnel. She entered the presence of a brilliant, wonderfully warm and loving light, and sensed that her soul was part of God and that everything in existence was created from the light (the breathing of God). But this extraordinary experience ended abruptly, as Reynolds’s deceased uncle led her back to her body—a feeling she described as “plunging into a pool of ice.”

Meanwhile, in the operating room, the surgery had come to an end. When all the blood had drained from Pam’s brain, the aneurysm simply collapsed and Spetzler clipped it off. Soon, the bypass machine was turned on and warm blood was pumped back into her body. As her body temperature started to increase, her brainsteam began to respond to the clicking speakers in her ears and the EEG recorded electrical activity in the cortex. The bypass machine was turned off at 12:32 p.m. Pam’s life had been restored, and she was taken to the recovery room in stable condition at 2:10 p.m.

Near Death Experience

Atheistic Hinduism Carvaka, Founder Brahaspati, Deva Guru


Indian Philosophy, Hinduism does not shun those who deny the existence of God.

It is taken as a point of view of Life.

Though philosophical arguments were engaged in rebutting the Carvakas, there not harassed nor branded as Atheists and ostracized.

Carvakas, Lokayatas Indian Philosophical System.image.jpg

Carvakas, Lokayatas Indian Philosophical System.

They were present during the Rig Vedic period, some 5000 years back and their later work is dated to be around 600 BC.

The CarvakaSyatem, the Indian Atheistic Hedonist Syatem is also also called  Lokayata.,(worldly wise)

The flip side of this is that the Charvaka’s first Text,the primary source, which is lost to us , is credited to Bruhaspati, the Guru,Preceptor of the Devas!

This shows that though one is a Realized soul, Bruhaspati is One, one is not averse to exploring the other views as well and even propagated one so that to who ever these thoughts appealed they might follow.

Kapila, who is an Avatar of Lord Vishnu is the founder of Samkhya Philosophy,which denies God!

Samkhya is considered s one of the most respected philosophical systems of India.

Hinduism does not differentiate between one who believes in God and one who does not.

Astika system is one that believes in the Authority of the Vedas and others who do not accept the Vedas, Sabda, as the authority are called Nastikas.

Carvakas, Jainism, Buddhism and Ajivika are Nastika systems.

What does Carvakas say?

Carvakas do not believe in God, Vedas.

They do  not believe in Rebirth and Karma or ceremonies.

They take Perception only as the means of knowledge and deny even inference as an Instrument of Knowledge.

Inference, the process by which, we come to know of things by things that are present before us.

The presence of electricity is inferred by the results it produces,like Light, Sound .

Carvakas, do not admit this knowledge , saying that the conditions for this inference may not always be correct.

They imply that One result may be caused by more than one Cause.

This is rebutted by Advaita and it proves that Inference is an essential tool, by describing Parinamavada and Vivartahvada, that is Cause is contained in the Effect and Effect in the Cause.

I shall write on this in detail.

For the Carvakas, Pleasure is the only Goal.

On Death, Birth, origin of the Universe , they brush every thing aside by saying it is Nature.

They do not go into the point of what Nature is.

This enquiry is done by the Astika systems like Samkhya, Yoga, Nyaya, Vaiseshika,Mimamsa and Vedanta, apart from Vedas, which deals with this subject in detail.

Cārvāka means “agreeable speech” or “sweet talkers” (चारु, cāru – agreeable, pleasant or sweet and वाक, vāk – speech). Its traditional name, Lokāyata (Sanskrit: लोकायत) signifies “directed towards, aiming at the world” (लोक, loka which means “worlds, abode, place of truth, people”, and आयत, āyata means “extended, directed towards, aiming at”

Some observations by Carvaka.

‘The Carvaka epistemology holds perception as the primary and proper source of knowledge, while inference is held as prone to being either right or wrong and therefore conditional or invalid Perception are of two types, for Carvaka, external and internal. External perception is described as that arising from the interaction of five senses and worldly objects, while internal perception is described by this school as that of inner sense, the mind. Inference is described as deriving a new conclusion and truth from one or more observations and previous truths. To Carvakas, inference is useful but prone to error, as inferred truths can never be without doubt. Inference is good and helpful, it is the validity of inference that is suspect – sometimes in certain cases and often in others. To the Cārvākas there were no reliable means by which the efficacy of inference as a means of knowledge could be established…

Cārvākas denied metaphysical concepts like reincarnation, extracorporeal soul, efficacy of religious rites, other worlds (heaven and hell), fate and accumulation ofmerit or demerit through the performance of certain actions.Cārvākas also rejected the use of supernatural causes to describe natural phenomena. To them all natural phenomena was produced spontaneously from the inherent nature of things.

The fire is hot, the water cold, refreshing cool the breeze of morn;
By whom came this variety ? from their own nature was it born.

Consciousness and afterlife.

There is no other world other than this;
There is no heaven and no hell;
The realm of Shiva and like regions,
are invented by stupid imposters.

—Sarvasiddhanta Samgraha,  Verse 8 [

The Sarvasiddhanta Samgraha states the Carvaka position on pleasure and hedonism as follows,

The enjoyment of heaven lies in eating delicious food, keeping company of young women, using fine clothes, perfumes, garlands, sandal paste… while moksha is death which is cessation of life-breathe… the wise therefore ought not to take pains on account ofmoksha.

A fool wears himself out by penances and fasts. Chastity and other such ordinances are laid down by clever weaklings.

—Sarvasiddhanta Samgraha,  Verses 9-12
No independent works on Cārvāka philosophy can be found except for a few sūtras composed by Brihaspati. The 8th century Tattvopaplavasimha of Jayarāśi Bhaṭṭa withMadhyamaka influence is a significant source of Carvaka philosophy. Shatdarshan Samuchay and Sarvadarśanasaṅ̇graha of Vidyaranya are a few other works which elucidate Cārvāka thought.
Lord Rama had a detailed discussion with Jabali, a Carvaka, Please read my post on this.
