Many questions are raised among Indian philosophers on the exact meaning of certain passages occurring in the preceding paragraphs. First, as to who is admitted to the path of the Devas? Householders, who know the secret doctrine of the five fires or the five libations of the Agnihotra, as described above, while other householders, who only perform the ordinary sacrifices, without a knowledge of their secret meaning, go by the path of the fathers. Secondly, those who have retired to the forest, and whose worship there consists in faith and austerities, i. e. Vanaprasthas and Parivragakas, before they arrive at a knowledge of the true Brahman. The question then arises, whether religious students also enter the path of the Devas? This is affirmed, because Puranas and Smritis assert it, or because our text, if properly understood, does not exclude it. Those, on the contrary, who know not only a conditioned, but the highest unconditioned Brahman, do not proceed on the path of the Devas, but obtain Brahman immediately.

Again, there is much difference of opinion whether, after a man has been in the moon, consuming his works, he can be born again. Birth is the result of former works, and if former works are altogether consumed, there can be no new birth. This, however, is shown to be an erroneous view, because, besides the good sacrificial works, the fruits of which are consumed in the moon, there are other works which have to be enjoyed or expiated, as the case may be, in a new existence.

The great difficulty or danger in the round of transmigration arises when the rain has fructified the earth, and passes into herbs and trees, rice, corn, and beans. For, first of all, some of the rain does not fructify at once, but falls into rivers and into the sea, to be swallowed up by fishes and sea monsters. Then, only after these have been dissolved in the sea, and after the sea water has been attracted by the clouds, the rain falls down again, it may be on desert or stony land. Here it may be swallowed by snakes or deer, and these may be swallowed by other animals, so that the round of existence seems endless. Nor is this all. Some rain may dry up, or be absorbed by bodies that cannot be eaten. Then, if the rain is absorbed by rice, corn, &c., and this be eaten, it may be eaten by children or by men who have renounced marriage, and thus again lose the chance of a new birth.. Lastly, there is the danger arising from the nature of the being; in whom the food, such as rice and corn, becomes a new seed, and likewise from the nature of the mother. All these chances have to be met before a new birth as a Brahmana, Kshatriya, or Vaisya can be secured.
