"The total material substance, called Brahman, is the source of birth, and it is that Brahman that I impregnate, making possible the births of all living beings, O son of Bharata."

Sri Krishna tells Bharata [Arjuna] that He creates the Universe. We might get a doubt. Why should the Lord talk of creation in this context? Our topic has been the association of the Three qualities in samsaram or our body, and this association develops desires and make us to have rebirths on and on. The Lord, but now, says that He only created all living beings including lord Brahma and an obscure grass, from Moola prakruti. In Moolaprakruti, these Three qualities are integral part. Since the bodies are formed out of Moolaprakruti, the Three qualities are also in the bodies created. The Lord is going to expalin how the atman is bonded in this body, which has in-built Three qualities. In this sloka the Lord tells about the stage before all living beings are born. Mahad brahma = large, vast and enormous prakruti, yoni = cause [for all living beings], mama = is Mine [Sri Krishna's]. We had seen earlier how the entire Universe emerged from Him. Tasmin = in that, sarva bhutanam = every living beings are, garbham = impregnated, dadhamyaham = by Me [Sri Krishna]. In this very vast Moola prakruti, the Lord impregnates all living beings. It is like when male and female intercourse, the semen of the male is impregnated into the female womb. The Lord fertilizes Moolaprakruti with atman of all living beings. From such impregnated Moolaprakruti, all living beings, starting from lord Brahma to a tiny insect or worm or grass, get created. Sriman Narayana is the cause for creation of impregnated Moolaprakruti. Aham dadhami means the Lord says that He fertilizes Moolaprakruti with the entity of jeevatman. By this Sankhya philosophy is condemned. According to Sankhya philosophy, enunciated by sage Kapila, only prakruti and atman are responsible for creation and the Lord has no role in that process. But Sri Krishna categorically says here that He fertilizes atman into prakruti. Tata = hence [by this fertilization of atman in prakruti by the Lord], sarva-bhutanam = all living beings, sambhava = births, bhavati = happen. Thus the Lord fertilizes all atman into prakruti. From this impregnated prakruti every living being is born. There is another doubt in this sloka and it has the answer also. We will see that question and answer later.
