nānto’sti mama divyānāṃ vibhūtīnāṃ paraṅtapa |
eṣa tūddeśataḥ prokto vibhūter vistaro mayā || 40 ||
Translation
O mighty conqueror of enemies(Arjuna), there is no end to My divine manifestations. . What has been decribed by Me is but a mere indication of My infinite opulence.
Purport
Bhagwan Shri Krishna after describing his many manifestations(forms) explains in this Shloka that those forms which described are just for an indication. In reality, Bhagwan Shri Krishna has no end of Manifestations.
In earlier Shloka(#39) Bhagwan Shri Krishna has already described that everything in this universe is originated from him only, The details of the same have been given in different ways at many places in Shrimad Bhagvad Gita, Chapter 7 describes the same naming the specific elements.
Earth, water, fire, air, ether, mind, intellect and the principle of ego; thus My material nature [Prakṛti] is divided eightfold.
--Ch7:sh4
Besides this inferior nature, O mighty-armed Arjuna, there is a superior energy of Mine. It is the life-principle [Jīva-bhuta], by which this universe is sustained.
--Ch7:Sh5
Generally, the human is wired to identify only concrete objects and what forms described in this chapter are just some of those. but manifestation(Vibhuti) is one of the very core phenomena of the evolution of the universe. From the beginning to the existence of a concrete object, it passes through many stages of manifestations, some of them temporary.
