That is the purpose of spirituality: to realize yourself as that Brahman … Vedanta says you and the other are not separate. You and the other are one reality.
When you know yourself truly as you are, you will know the reality … Our reality is the ultimate reality. God is our own reality. You are Brahman. This is the ultimate reality.
The Upanishads contain perhaps the most ancient living teachings on spirituality. Spirituality at its most original and fresh … The basic teaching of the Upanishads is that there is an ultimate reality—this world that we experience, and how we experience ourselves, are all manifestations of that reality. We are that reality. If only we would know ourselves truly, we would realize ourselves to be that absolute reality. That absolute reality in the Upanishads is called ‘Brahman.’ Brahman literally means ‘the vast’. That is the closest word you’ve got in Vedanta to God.
