Bhagavad Gita, Chapter 11, Verse 39

You are Vâyu, Yama, Agni, Varuna, the Moon, Prajâpati, and the Great-Grandfather. Salutation, salutation to You, a thousand times, and again and again salutation, salutation to You!

Real, repeated bowing here matches the scale of what's just been recognized, once clearly isn't enough.

Naming so many distinct gods as manifestations of one source, then bowing again and again, shows devotion trying to match the size of what it's responding to. Real repetition here isn't excess, it's proportional.
