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.
Birth does not lead to greatness; but cultivation of numerous virtues by a man leads him to greatness.
They are forever free who renounce all selfish desires and break away from the ego-cage of ‘I’, ‘me’, and ‘mine’ to be united with the Lord. Attain to this, and pass from death to immortality.
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.
