To be free is not merely to cast off one’s chains, but to live in a way that respects and enhances the freedom of others
Excessive attachment to sense pleasures leads to bondage, and detachment from sense pleasures leads to liberation; therefore it is the mind alone that is responsible for bondage or liberation.
Good is that which elevates the mind and evil is that which degrades the mind. Social virtue and vice are temporal entities; they have nothing to do with your relationship with the Supreme.
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.
