Bhāvam means the spiritual nature. Yaḥ prayāti sa mad-bhāvaṁ yāti. Mad-bhāvam means just like the nature or the transcendental nature of the Supreme Being. As we have described above, that the Supreme Lord is sac-cid-ānanda-vigraha (Bs. 5.1). He has His form, but His form is eternal, sat; and full of knowledge, cit; and full of bliss, ānanda. Now just we can compare our present body, whether this body is sac-cid-ānanda. No. This body is asat. Instead of being sat it is asat.
