Etha vaanasya Mahima Athojyaayam Gachcha Poorushah I
Paathosya Viswa Boothanni Thripaathasyamrutham Dhivi II
Ethavvan-Whatever is seen
Boothaani Viswa-whatever in the Universe
Divi-not of here,in Heavens.
Whatever is seen here is His Expressions .
Purusha is Greater than all this.
Whatever is expressed (here) is only a quarter of His (attributes)
Rest is not expressed,in Heavens.
After the next stanza the actual Evolution of the Universe will be described in a highly allegorical Language.
The Reality, according to Hinduism is a Principle.
More specifically Energy.
Two primordial energies are listed.
Another is Purusha the Kinetic Energy.
These two energies are the two facets of One energy, as Science would tell us.
Energy is One.
We name them as different to enable us to understand its workings.
The energy that has the potential to perform is Potential Energy.
That which Performs or induces Performance is Kinetic Energy or Energy in Action or on the Move.
This is Purusha of Hinduism.
Motion is not visible with out both working in tandem.
From the One basic Reality, Its attributes,Purusha and Parkriti become Universe.
