Saptha Rishis Change Abhijit Nakshatra Astronomy Validates

The concept of Saptha Rishis is known to Hindus.

These are the seven Sages who are to be accorded the highest respect and their works are believed to be the most authentic for the Manvanthara, a Time Scale to Indian Philosophy.

In performing any Hindu rite the mention of the Saptha Rishis is mandatory.

They are the Patriarchs of the Vedic Religion.

For the present Manvantara, the list is,

Atri, Bhrigu, Kuthsa,Vasishta,Gauthama,Gauthama Angirasa.

There is a variation of this as well,

Bhrigu, Atri, Angirasa Vashista, Pulastya, Pulalaha and Kratu.

Sanatana Dharma states that these Rishis change for each Manvanthara.

Manvantara is the astronomical time within an aeon or Kalpa, a “day (day only) of Brahma”, like the present Śveta Vārāha Kalpa, where again 14Manvantaras add up to create one Kalpa.

Please read my post on Manvantara.

Seventh, the present Manvantara.

Kashyapa, Atri, Vashista, Vishvamitra, Gautama, Jamadagni and Bharadvaja.

* there is a differnce in the name of the Rishis for the present Manvantara.

Hindu scriptures declare that the Saptha Rishis change as well as The Pole Star, The Dhruva Nakshatra.

This is validated by Modern Atronomy.

Lord Krishna in The Bhagavad Gita says.


‘I am Arjuna among Pandava and Abhijit among Nakshatras’.

Abhijit is the unseen Nakshatra in Hinduism , the twenty-eighth.


Abhijit is the Sanskrit name for Vega, the brightest star in the northern constellation of Lyra.

Abhijit means “Victorious” or “the One who cannot be defeated”.

This also changes for Manvantaras.


“Once Pluto moved into 10 degrees of Capricorn, it came within orb of Vega, another of astrology’s famous fixed stars.

Vega is one of the brightest stars in the sky – the 5th brightest in the whole of the sky. Back around 12,000 BCE, it was Earth’s pole star. And such cycles being what they are, it will be Earth’s pole star yet again – just prior to the year 14,000 CE…


Vega was Pole Star 12000 BC.jpg
Earth procession of precessional pole stars (Note: all the years in this diagram have been rounded off to make it something south of a migraine to create.)
from an Earthly ‘pole pointer perspective’ means Planet Earth is currently pointed almost as ‘away’ from Vega as Earth will ever get. If a planet can ‘look away’ from something, Earth has another 800+ years to go, and it will be ‘pointed’ in as opposite a direction as it can get from Vega. And that’s a rather interesting notion, considering that the astrological Vega is known to be a charismatic position.”

It may be noted that Vasishta was the Kula Guru of Dasaratha and Lord Rama and Ram’s date is around 5000  BC.


UFO Landing Site Samaipata

The authorities all over the world are in constant Denial Mode when confronted with anything connected with UFO.

There is enough evidence to at least institute a Study on the UFOs.

Please check under astrophysics, interesting and Funny, Videos for more information on UFO, Aliens.

There are cave paintings all over the world depicting Astronauts like figures with hoods,figures resembling Flying Saucers.

One such is found in Chattisgarh and nother in Mahabalipuram, Tamil Nadu.

Ravanas’ Puspaka Vimana Ale has been found in Lanka(Read my post)

Please read my post on this.

There are also some places where patterns are observed.

The Nazca Lines of Peru and Crop Circles.

There is Samaipata, Bolivia, where at 6500 feet above sea level, is rock marked with aligned lines, possibly a landing site for UFOs.

This is what Erich Von Daniken proposed in the 60’s.

I am curious about the name.

Samai is time/right time in Sanskrit, Hindi, Samaya in Kannada Samayam in Tamil.

Peta is the corrupt form Betta , Mountain peak.

Any connection with Santana Dharma?

Sugreeva had his army look for Sita in Peru and the Nazca Lines resemble Shiva’s Trisula.(read my post)


El Fuerte de Samaipata: (‘Fort’ Samaipata).


Archaeology of the site has revealed that several phases of occupation were present at Samaipata. Before the Spanish were the Inca, and beneath the foundations of the Inca works evidence of previous cultural works was found, proving that the site was in use a long time before the might Inca. (5) So who were the people that originally carved the hill..? The site is now generally considered to be a pre-Incan site, built by the Chané people, a pre-Inca culture of Arawak origin, (3) who migrated from Guyana approximately 2,500 years ago. (6) It is suggested that the first engravings at El Fuerte were undertaken during the Mojocoyas period (AD 200 – 800) (7). Unfortunately, the exact chronology of the site is yet to be determined for the period between the Chané and the Inca, but the evidence suggests that there is more than one building phase at Samaipata.

The site was later occupied by the Inca who used it as their most advanced post of the Empire, of which it marked the frontier from the late 15th century until its fall in 1530. It was the administrative centre in charge of maintaining the order of the Inca in the region, but its principal function was keeping at bay the frequent invasion attempts of the Guarani Indians. (1) They gave it the name of “Samaipata”, which is Quechua (language of the Inca’s) and stands for ‘The Height to Rest’ or ‘Rest in the heights’, and they added several classic Inca-style masonry constructions to the complex. Around 1540 the Spanish arrived and encountered an Inca fortress. They renamed the site “El Fuerte” or “The Fortress”, and deserted the site around 1629 when they founded the settlement known today as Samaipata a few Km away

Starting at the western end, the rock has been carved to reveal the outline of three felines (jaguars). The second is out of shot (right, foreground), and is greatly eroded. The third is placed further ahead within what appears to be the zig-zag motif common in Inca and Tiahuanacan art.





The two parallel lines are oriented to the eastern sky at a position of azimuth 71° and an altitude of about 6.75° .


‘The orientation of the carved trail is the direction of the rise of the Pleiades at about 1AD. An observer at the top of the hill could see the rising of the Pleiades at around 500AD, and also the rising of Regulus in 600AD. The alignment of the 8 pits points to the rise of the Pleiades at 500BC and of Aldebaran at 500AD. The long rectilinear engraving near the seats complex to the East matches the rise of the Pleiades at about 500BC.

If we consider that the Pleiades cluster (‘Collca’ in the quechua or ‘Qutu’ in the aymara languages) was important in the Andean world as a celestial signal for sowing (mainly maise) or for the prediction of yields, then it is possible to think that the alignments found at Samaipata were devised for the observation of this star cluster. Accordingly, the monument should have been built between 1AD and 500 or 600AD. Perhaps the eight pits were used first and the ‘cascabel’ later on, as a more recent construction. Of course only the archaeological research may work out a precise dating for the monument. (2)


World's Largest Number.png

Large Numbers Modern Maths Tamil Classics

In the highly complex world of Astronomy, where very huge distances are to be measured special numbers are needed to count.


The presence of Large numbers indicate that knowledge of such huge numbers were necessitated .


That is possible only when Knowledge of such numerals are needed.

World's Largest Number.png
World’s Largest Number.


And such a field is Astronomy.


Unless one has a very deep insight into the working of the Universe , one would not have devised the numbers and more importantly  would not have systematized them.


The largest Number used now ,


When a number represents a quantity rather than a count, SI prefixes can be used—thus “femtosecond”, not “one quadrillionth of a second”—although often powers of ten are used instead of some of the very high and very low prefixes. In some cases, specialized units are used, such as the astronomer’s parsec and light year or the particle physicist’s barn.

Nevertheless, large numbers have an intellectual fascination and are of mathematical interest, and giving them names is one of the ways in which people try to conceptualize and understand them.

One of the first examples of this is The Sand Reckoner, in which Archimedes gave a system for naming large numbers. To do this, he called the numbers up to a myriad myriad (108) “first numbers” and called 108 itself the “unit of the second numbers”. Multiples of this unit then became the second numbers, up to this unit taken a myriad myriad times, 108·108=1016. This became the “unit of the third numbers”, whose multiples were the third numbers, and so on. Archimedes continued naming numbers in this way up to a myriad myriad times the unit of the 108-th numbers, i.e., (10^8)^{(10^8)}=10^{8\cdot 10^8}, and embedded this construction within another copy of itself to produce names for numbers up to \left((10^8)^{(10^8)}\right)^{(10^8)}=10^{8\cdot 10^{16}}. Archimedes then estimated the number of grains of sand that would be required to fill the known Universe, and found that it was no more than “one thousand myriad of the eighth numbers” (1063)….


The Largest Standard Dictionary Number, on date, is, Centillion ,10303.


Tamil Classics name, 1,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,000 = MAHAYUGAM = Ten Undecillion = 10 37.


This is 10 steps later to Decillion.


That is adding the power.


The basic computation in a Language that is over 5000 Year old….?

First Nakshatra Ashvini,Moola or Krittika?

There seems to be some debate on which is the Nakshatra in Hindu system.


Normally we take Aswini Nakshatra as the first Nakshatra and this is being followed every where among Hindu Households.


But there are views that it might be Krittika, Moola , based  on Vedic Astronomical calculations in the Atharva Veda.


1.Moola as the First Nakshatra.


If one star is to be identified as Moola, then the best candidate for Moola or Vichruta Nakshatra is 42 q OPH from Ophichius zodiac of the European system. It falls in the star band and is 50 minutes or 13 degrees (E-W) away from Jyeshta. Its brightness is +3.28. Arab Sabik is another strong candidate for Moola with +2.43 brightness and is also 13 degrees from Jyeshta.

Sagittarius,Dhanus Constellation.jgif
shows 30 degrees square area around Dhanu Raashi. The Nakshatras in this figure are Vichruta/Moola, and Poorvaashada. Both the stars are in the moon traverse band. For the imaginative, a stretched bow can be seen in the Dhanu Raashi. Vichruta or Moola Nakshatras considered to be a star mansion with eleven stars

Moola or Vichruta has been extensively referred to in Atharveda Kaanda 2,Kaanda 3 and kaanda 6 (Ref 2). Vichruta, stands for darkness and Moola carries an adjective Arishta. This word has two meanings, one standing for sweet and second associated with bad associated with death. Astronomically, Moola is in line with Milkiway galactic center. Did some astronomical event appear 5000 years ago near the center of Milkiway galaxy, which could explain why Moola is considered as bad? In modern astronomy, there have been conjectures of a black hole at the center of our Milkiway. This area of sky is visually dark because large amount of matter is presumed to exist around the center of the Galaxy. Did vedic period astronomers know of the center of the galaxy or did they see some astronomical event justifying the bad omen associated with Moola?.

Poorvaashaada Nakshatra is considered to be a star mansion of two stars. The following table presents candidate stars, which qualify as Poorvashaada based on brightness, location with reference to moon traverse band, and distance from previous Nakshatra.

2″Krittika as the First Nakshatra.

1. Rishi Gargya starts the list of twenty seven nakshatra‘s starting with Krittika. Choice of Krittika as the first of twenty-seven is very significant. In contrast Jyotishya Shaastra uses Ashwini as the first star. The choice of first Nakshatra must correspond to a logically first day of a solar year, which dictates the weather cycles. Which is the year’s first day? Astronomically speaking, the spring Equinox day in Northern Hemisphere temperate zone is a logical one. It heralds the arrival of the spring, in temperate zone of northern hemisphere of the earth. Vasantha ritu, the spring has always been considered as beginning of a year from Rig-vedic times. Hence, the first observation implicit in Rishi Gargya’s sooktha is that on spring Equinox day, Sun was at Krittika Nakshatra. Figure 13 shows Sun location on March 21, 2400 BC from Load Star Pro. The Sun is on equator and is pointing to Krittika nakshatra.

Gargya Rishi! Nakshatrani Devata! Trishtup-Bhurik Chandaha!

Chitrani sakam divi rochanani sarisrupani bhuvanejavani

turmisham sumatimichaamaano ahaani geerbhi saparyami nakam!1!

suhavamagne krittika rohini chaastu bhadram mrigashirah Sham aardhrah !

punarvasu soonruta chaaru pushyo Bhaanur aslesha ayanam magha mey !2!

punyam poorva Phalguni chottra hasta schittra shiva swaati sukho mey astu!

raadhe vishaakhe suhav anooradha jyeshta sunakshatramarishta moolam !3!

annam poorva raasataam aashadha oorja devy uttaraa aavahantu!

abhijinma raasataam punyameva shravanah shravishtaah kurvatam supushtim!4!

Aa mey maha chatabhishagam vareeya Aa mey dvaya proshtapadaa susharma!

Aa reyvato chashvayujow bhagam ma Aa mey rayim Bharanya aavahantu!5!

This Sookta dedicated to Nakshatra‘s was recorded (Drashtaara) by Gargya Rishi. The Sookta describes both astronomical and astrological elements. Twenty eight Nakshatras are identified starting with Krittika and reference is made to Ayanam occurring in Maghaa. A nakshatra Abhijit is shown between Uttarashadha and Shravana. Its use has been discontinued in the Jyotishya with only twenty seven identified currently. The authenticity of the Athrarvana texts is well accepted, by the very reverence shown towards precise learning. Hundreds of generations of Shrotreeya’s have carried veda‘s down to us in its original language using oral traditions of Krama, Pada, Jatha, and Ghana Paatha so that distortions are nonexistent. Two major astronomical time markers are evident and implicit in the Sooktha.

Higher Astronomy Instruments Designs Surya Siddhanta

Many are under the impression that Hinduism, especially the Vedas are theoretical and do not address to the problems of daily Life or Science.


Nothing can be farther from the Truth.

I had posted articles on practical application of Science,Dealing with daily life, Botany,Zoology, Food and other vital subjects that deal with our daily needs, developed by Hinduism.


Here I am furnishing details from the Surya Siddhanta that deals with Astronomy in detail.


I had earlier posted an article on Vishnu’s Navel Galaxy and how it has been validated by modern Astronomy.


The Surya Siddhanta is one of the oldest treatises (siddhanta) in Hindu astronomy. The extant text as edited by Burgess (1860) is medieval (c. 12th century), but it is clearly based on older versions, which may go back to before the Common Era[citation needed].

It has rules laid down to determine the true motions of the luminaries, which conform to their actual positions in the sky. It gives the locations of several stars other than the lunar nakshatras and treats the calculation of solar eclipses. as well as solstices eg.summer solstice 21/06 Significant coverage is on kinds of time, length of the year of gods and demons, day and night of god Brahma, the elapsed period since creation, how planets move eastwards and sidereal revolution. The lengths of the Earth’s diameter, circumference are also given. Eclipses and color of the eclipsed portion of the moon is mentioned.”
