Bhagavad Gita, Chapter 11, Verse 5

The Deity said: Behold, O son of Prithâ, by hundreds and thousands, My different forms celestial, of various colours and shapes.

What's offered here is described as real abundance, not one single fixed shape.

Krishna's answer doesn't narrow the vision down, it opens it wide, countless shapes, sizes, and colors at once. Real scale is set from the very first word of the response.
