"Now this self, verily, is the world of all beings. In so far as he makes offerings and sacrifices, he becomes the world of the gods. In so far as he learns (the Vedas), he becomes the world of the seers. In so far as he offers libations to the fathers and desires offspring, he becomes the world of the fathers. In so far as he gives shelter and food to men, he becomes the world of men. In so far as he gives grass and water to the animals, he becomes the world of animals. In so far as beasts and birds, even to the ants find a living in his houses he becomes their world. Verily, as one wishes non-injury for his own world, so all beings with non-injury for him who has this knowledge. This, indeed, is known and well investigated."  Fourth brahmana, p90
