tayor vivāho maitrī ca
Persons of superior and inferior qualities may live together in a relationship of master and servant or teacher and student, but marriage and friendship are proper only between those of equal status. The word bhava, in the context of marriage, indicates that a couple should have a similar capacity to produce good offspring.
Lord Kṛṣṇa here presents Himself as materially unqualified. In fact, the Lord does not have any material qualities: He lives in pure spiritual existence. Thus all the Lord’s opulences are eternal and not of the flimsy mundane sort.
