What is our Duty?

We all are eternal souls, and as described in the Bhagavad Gita, a soul is always pure, full of knowledge and bliss. It is just that our ignorance covers our true nature and once we purify our consciousness we realize our duties, to serve the Supreme Personality of Godhead, Krishna. And once we become aware of it, we become liberated from all material anxieties and become eligible to enter into the spiritual realm which is free from any stress or suffering.
