To be free from bondage the wise person must practise discrimination between One-Self and the ego-self.
By that alone you will become full of joy, recognising Self as Pure Being, Consciousness and Bliss.
Loud speech, profusion of words, and possessing skillfulness in expounding scriptures are merely for the enjoyment of the learned. They do not lead to liberation.
Do not look at anybody in terms of friend or foe, brother or cousin; do not fritter away your mental energies in thoughts of friendship or enmity. Seeking the Self everywhere, be amiable and equal-minded towards all, treating all alike.
