What is the Atma?

What is the Atma? The Atma is the name that we give for God's presence in our heart. Now what happened is that for someone to meet the Nirguna directly seems impossible. For someone to meet the Saguna, which is the boundless phenomenality of God that takes birth in God's presence, is also impossible. We can't even imagine a thousand oranges in our head, so how will you meet the Saguna Brahman? We can't. So my version of this is that God realized that we are too limited in our faculties. So He made Himself accessible to us in the form of a very simple, organic presence of being in our hearts. That beingness, He has made it so impossible to miss because that which we call the I am itself is that beingness.
