14 – 15 - 16. From food are born the creatures; from rain does food become possible. By sacrificial act do the rains come to be and the sacrifice comes about from action.Know the action to be born from Brahman and Brahman is revealed by the immutable (Vedas). Consequently, all-comprehending Brahman is eternal, established in sacrifice. The cycle thus set in motion, whosoever fails to maintain, he is evil, reveling in senses and he, O Partha, lives in vain.
Bhashya :- Another purpose is proposed here in the verse „From food‟ etc. Sacrifice and the rains are said to be the result of such offering of food. The earlier reference of sacrifice in cyclical form is not made here. Only the future course of the actions is indicated. These actions are not recommended merely for the sake of similarity. Of course, the clouds are the generating force for the rains, which, in turn, are born out of sacrifice. “When the oblation is offered in (sacrificial) fire in the prescribed manner, it reaches the Sun. From the Sun the rains are produced, food from the rains and thereafter the creatures”, thus, speak the scriptures. There is no contradiction in both the statements that the rains are the product of the Sun and the Ocean. Thus out of the sacrifice, the rains are produced. The offering of oblations to the Gods is referred as sacrifice. Actions are the other acts to be performed.
