BG Chap 10 - The vibhūtis of Kṛṣṇa - 66 thru 70

(66): He is the splendor of the splendid.
(67): He is the victory of the conquerors,
(68): the endeavor which yield results of those who endeavor, and
(69): the strength of the strong. When Kṛṣṇa was present on earth, no one could surpass Him in strength. Even in His childhood He lifted Govardhana Hill.
(70): Among Vṛṣṇis, Kṛṣṇa is Vāsudeva. Baladeva Vidyābhūṣaṇa says Vāsudeva, the son of Vasudeva, here refers to Balarāma and not to Kṛṣṇa, because it is wrong to call His svarūpa a vibhūti. Viśvanātha Cakravarti says that Vāsudeva refers to Vasudeva, Kṛṣṇa’s father. Sometimes the long ā can have the same meaning as short a. The long ā is used to indicate self-interest. Though Kapila and others mentioned in this chapter as vibhūtis are directly the Lord, and thus the creators and destroyers of the material world, calling them vibhūtis is acceptable, by meditating on them as avatāra expansions of Kṛṣṇa. It should be understood that the expansions, though non-different from Kṛṣṇa in potencies, do not manifest all of the potencies or qualities in their particular forms.
