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.
