3.14 अन्नात् from food, भवन्ति come forth, भूतानि beings, पर्जन्यात् from rain, अन्नसम्भवः production of food, यज्ञात् from sacrifice, भवति arises, पर्जन्यः rain, यज्ञः sacrifice, कर्मसमुद्भवः born of action.Commentary: Here Yajna means Apurva or the subtle principle or the unseen form which a sacrifice assumes between the time of its performance and the time when its fruits manifest themselves.
