IV. -STMndogya-Upanishad V. 10, 1 :

' Those who know this, and those who in the forest follow austerity as faith, go to the light (ar&is), from light to day, from day to the waxing half of the moon, from the waxing half of the moon to the six months when the sun goes- to the North, from the six months when the sun goes to the North to the year, from the year to the sun, from the sun to the moon, from the nioon to the lightning. There is a person, not a man, he leads them to Brahman. This is the Path of the Gods.

JOURNEY OF THE SOUL AFTER DEATH. 119
* But those who in their village practise charity as sacrifice and pious works, go to the smoke, from smoke to night, from night to the other (waning) half of the moon, from the other half of the moon to the six months when the sun moves to the South. But they do not reach the year. From the months they go to the world of the Fathers, from the world of the Fathers to the ether, from the ether to the moon. That is Soma, the King. That is the food of the gods, the gods feed on it. Having tarried there, as long as there is a rest (of works), they return again on the way on which they came, to the ether, from the ether to the air (vayu). When he has become air he becomes smoke, having become smoke he becomes mist, having become mist he becomes a cloud, having become a cloud he rains down. Then they are born1 as rice and corn, herbs and trees, sesamum and beans. From thence the escape is very difficult. For whoever they are who eat that food and scatter seed, he be- comes like unto them. Those whose conduct has been good will probably attain some good birth, the birth of a Brahma-na, or a Kshatriya, or a Vaisya. But those whose conduct has been evil will probably attain an evil birth, the birth of a dog, or a hog, or a /camZala. On neither of these two roads do those small, oft-returning creatures proceed. Theirs is the third state, of which it is said, " Live and die." '
