1.16 - Astavakra Geeta - Chapter 1 Verse 16 - Omnipresent
You have pervaded this entire universe; really, you have pervaded it all. You are pure knowledge, don't get disheartened . ॥1.16॥
In the last few verses, we have seen that we are nothing but consciousness. And consciousness is pervaded everywhere in the entire universe. Consciousness is present there whatever we can be conscious about. Therefore no place in the universe is left untouched by consciousness. And since the unchanging factor in us, which is constant devoid of time and place, is consciousness. Therefore we can say "I am pervaded this entire universe".
And ultimately after learning each and every knowledge, what pure knowledge says. It says we are the whole, We are the cosmos, we are consciousness, we are the world. That is the ultimate and pure knowledge. And since everything is present in us, this pure knowledge is in us. The pure knowledge is us.
