711. This verse evidently shows that there was dispute about Krishna's supremacy, as Professor Weber guesses. The Krishna-cult was at first confined among a small minority, Sisupala's and Jarasandha's unwillingness to admit the divinity of Krishna distinctly points to this.
712. This is certainly a very fanciful etymology of the word Sanatana which ordinarily implies eternal.
713. Atma Atmanah is explained by Nilakantha as jivasya paramarthikam swarupam.
714. Swamatmanam is Pratyathatmyam.
715. The sense is that when all men are equal in respect of their material cause, why are such differences in the srutis and the smritis about the duties of men?
716. The meaning seems to be this: in the beginning of every celestial yuga, i.e., when the Supreme Being awaking from sleep desires to create creatures anew, and creatures or beings start again into life. With such starting of every being, the rules that regulate their relations and acts also spring up, for without a knowledge of those rules, the new creation will soon be a chaos and come to an end. Thus when man and woman start into life, they do not eat each other but combine to perpetuate the species. With the increase of the human species, again, a knowledge springs up in every breast of the duties of righteousness and of the diverse other practices, all of which help to regulate the new creation till the Creator himself, at the end of the yuga, once more withdraws everything into himself.
717. i.e., the body.
718. What is meant seems to be this: there can be no river without water. A river cannot exist without water. When a river is mentioned, water is implied. The connection between a river and water is not an accident but a necessary one. The same may be said of the sun and its rays. After the same manner, the connection between the Soul and the body is a necessary one and not an accident. The Soul cannot exist without a body. Of course, the ordinary case only is referred to here, for, by yoga, one can dissociate the Soul from the body and incorporate it with Brahma.
719. The mind has no existence except as it exists in the Soul. The commentator uses the illustration of the second moon seen by the eye in water, etc., for explaining the nature of the Mind. It has no real existence as dissociated from the Soul.
720. Swabhavahetuja bhavah is explained by the commentator as the virtuous and vicious propensities. (Swabhava purvasamskara; sa eva heturyesham karmanam layah bhavah). 'All else,' of course, means Avidya or Maya, which flows directly from Brahma without being dependent on past acts. The meaning, then, is this: as soon as the Soul takes a new form or body, all the propensities and inclinations, as dependent on its past acts, take possession of it, Avidya or Maya also takes possession of it.
