Everything is the Supreme Being, which is Existence – consciousness - bliss, and ‘I am That’. By constantly cultivating this pure thought, get rid of impure thoughts. Then discarding even that thought and always inhering in the state of fullness, you will become the non-dual and undifferentiated Supreme Being and attain liberation.
As you are externally aware, so also you can be inwardly aware of your thoughts and feelings, of your motives and urges, of your prejudices, envies, greed and pride…This outward and inward awareness is a unitary process which brings about a total integration of human understanding.
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments.
