Self-realization is that "I am neither American nor Indian nor black nor white, nor anything. I am a spirit soul, part and parcel of the whole, Kṛṣṇa." This is self-realization. So long it is not completely realized, so long we have got doubt, we have to make progress. And as soon as we come to the point and firmly convinced, that is self-realization.
Therefore here it is stated, "A self-realized man has no purpose to fulfill in the discharge of his prescribed duties." Prescribed duties, either take for... Any scripture. Take your Bible, take Koran, take Vedas. There are some prescribed duties. Just like in your Bible, there are ten commandments. "Thou shall not kill." So for whom? One who is not self-realized, one who is self-realized that "I am part and parcel of the Supreme God, everyone is part and parcel of the Supreme God and human being, animal, ant, aquatic, beasts, birds, every living entity is part and parcel of the Supreme Lord,"... That is self-realization. Then how can you kill? If everyone is part and parcel, son of the Supreme, how can you kill your brother? This is self-realization. You'll not... You'll hesitate even to kill even an ant.
Just like we published that picture in our Back to Godhead, "The Hunter." The hunter was taking pleasure in killing animals half dead, and when he was self-realized, he was hesitating to kill even an ant. You see? Why? Self-realized. So he has no prescribed duties. To him you haven't got to say, "Thou shall not kill." He will automatically not kill because he is self-realized. Self-realized person does not do any harm to anyone because he knows everyone in relationship with the Supreme. His central point is Kṛṣṇa
