Bhagavad Gita · Chapter 10: The Divine Glories
Bhagavad Gita 10.19
हन्त ते कथयिष्यामि दिव्या ह्यात्मविभूतयः ।
प्राधान्यतः कुरुश्रेष्ठ नास्त्यन्तो विस्तरस्य मे ॥
hanta te kathayiṣyāmi divyā hyātmavibhūtayaḥ | prādhānyataḥ kuruśreṣṭha nāstyanto vistarasya me ||
Very well. I will tell you of my divine manifestations, best of the Kurus, but only the chief ones, for there is no end to my extent.
Modern context
Krishna agrees, but warns that he can only name the chief ones, because there is no end to them. What follows is not a complete catalogue but a set of examples. The method is what matters: in any category, look at what is greatest, most radiant, most excellent, and see the divine there. Once the method is learned, the list can go on in one's own life without end.
