You have to examine the “scripture.”

What I am?  Who I am?

So whether you are talking about yourself, the truth of yourself or truth of the cause of this world, or an object in this world or the world in general, it will all end up in first, Ishvara, then afterward, Ishvara’s “intrinsic nature,” as one and the same. The “instrinsic nature” of the self, the “intrinsic nature” of the object and the “intrinsic nature” of Ishvara, is one and the same, the same limitless consciousness which is Brahman. 

Consciousness is.

Universe is in time and space.

Evident to you?  Yes.  Draws its existence from ‘is’ consciousness.  From I, “the Self,” it is the Self.  Self ‘is,’ is self-evident.  It is not objectified by anything, doesn’t need to be objectified.  Only one thing that doesn’t require to be objectified to say ‘is,’ it is the Self.  To which everything becomes evident.  Therefore what is self-evident is self-existent.  Self-evident means its existence is self-evident.  Doesn’t require a means of knowledge.  Therefore, the only one reality that exists and that is revealing itself in the form of consciousness, “existence” is “consciousness.”  

Existence, consciousness, limitless is the ultimate reality (Brahman).  He who knows that ultimate reality as existing in the intellect, which is in the highest space, he enjoys all his desires simultaneously in the form of the all-knowing Brahman.  The knower of Brahman gains the param — the ultimate.  An end that is unlike anything else.  So when you know “the ultimate reality,” you are knowing, “I am the whole.”  

I am the whole.  That’s what the knowledge of Brahman is.  The knower of Brahman gains the ultimate.  He is Brahman.  If Brahman is the whole, knowing the whole, I am not separate from it.  I am the whole.  

This wholeness is not unknown to you.  No distance can separate you from your happiness, the wholeness.  There is nothing that can deny this wholeness.  Therefore, we say the truth is Brahman, ayam atma brahma.  This Self is Brahman.  This ‘I’ is Brahman.  Limitless whole.  Partless whole. And, therefore we say cit — consciousness — is “existence.”  It is self-existent, self-evident.  Consciousness is “wholeness,” one whole.   Existence, consciousness, wholeness.  

Om.  That is whole, this is whole.  From that whole, this whole arises.  Removing this whole from that whole, the whole remains.
