Krishna uses a profound biological metaphor to explain the origin of life in the universe. He refers to the total unmanifested material energy (Mahat Tattva) as 'mahad brahma', which acts as the cosmic womb (yonir). Krishna states that He personally impregnates (garbhaṁ dadhāmy aham) this vast, inert material womb with the spiritual seeds (the living entities). From this divine union of spirit and matter, all living beings are born (sambhavaḥ sarva-bhūtānāṁ).
