Sanskrit
अन्नाद्भवन्ति भूतानि पर्जन्यादन्नसंभवः । यज्ञाद्भवति पर्जन्यो यज्ञः कर्मसमुद्भवः ॥
annād bhavanti bhūtāni parjanyād annasambhavaḥ yajñād bhavati parjanyo yajñaḥ karmasamudbhavaḥ
Translation
From food creatures become; from rain is the production of food; rain proceedeth from sacrifice; sacrifice ariseth out of action.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
A chain argument — creatures depend on food, food on rain, rain on sacrifice, sacrifice on action — that closes the causal loop verse 15 will name explicitly as a “wheel.” Each link is a real ecological dependency, rain does produce food, pressed into service as a metaphysical claim about action’s cosmic function, blurring agricultural fact and ritual theology in a way that’s characteristic of how this argument works.
