सर्वयोनिषु कौन्तेय मूर्तयः सम्भवन्ति याः।
तासां ब्रह्म महद्योनिरहं बीजप्रदः पिता।।14.4।।
14.4 O son of Kunti, whatever forms are born from all the wombs, of them the great-sustainer is the womb; I am the father who deposits the seed.
14.4 In all wombs such as those of gods, Gandharvas, Yaksas, Raksasas, men, animals, beasts, birds, serpents etc., whatever forms are generated, the brahman (Prakrti) is the great womb or cause. Beginning from Mahat and ending with the five elements, Prakrti, with the mass of conscient selves imbedded by Me in it, is the cause. I am the sowing father. The meaning is that I am the imbedder of the multiplex of conscient selves according to each ones Karma. Now, He teaches the cause of continuing births as divinities etc., of those born in this manner at the beginning of a cycle of creation. It is due to the conjunction of these beings with Prakrti, in keeping with their old Karmas:
