Let the mystery open with the story from Chandogya Upanishad ( 8th to 6th century BC ) .

Sage Uadalak is greeting the 24 Year old Svetaketu as he has returned as a distinguished Scholar after learning all the Vedas, but with excessive pride in oneself with micro vision of Logical Intelligence
His father who is a Spiritual Sage feel disillusioned after a pause , speak “Svetaketu, my child, you are so full of your learning but Have you known the one by knowing which you will know every one ?
Do you have now the Knowledge by which one can hear what can not be heard , by which one can see what can not be seen and by which one can know what can not be known ?
Svetaketu, honestly accepts the ignorance and sat down to listen to father’s wisdom.

“As by knowing one lump of clay all that is made of clay is known – so, my child, is that knowledge, knowing which we know all.” and Which is inherent in all .
Which is neither Feminine nor Masculine , neither Light nor Darkness, neither Sound nor Silence, neither Heard nor Unheard, neither Positive nor Negative, neither Taste nor Tasteless, only that which is Constant and Eternal pervades beyond Creation and Destruction so in Vedanta Vision of Hinduism describes this as NETI NETI …Neither this Nor that .
Energy Equation of Cosmos is Zero so is the Atom.
So we can Name it as ZERO which is before and after BIG BANG .
( The best-supported theory of our universe’s origin centers on an event known as the Big Bang. )
What is this ZERO ? which Many civilizations has given name as OM , Allah , God , Tao and many others ……. Why ….. we will explore in What is Enlightenment ? Part 4
Love all.
