33 KOTI GODS. NOT 33 CRORE GODS

People having either no knowledge or incomplete knowledge say that there are 33 crore gods in Hinduism whereas there is only One God and 33 deities:
The eight Vasus, the eleven Rudras, and the twelve Adityas-----these are thirty one. And Indra and Prajapati make up the thirty three--The Brihadaranyaka Upanishad: 3: 9: 2

Any number, whether 33 million or 33 crore or 33 thousand, except 33 is incorrect.

Which are the eight Vasus?
Fire, the earth, the air, the sky, the sun, heaven, the moon, and the stars-----these are the Vasus; for in them all this [universe] is placed (vasavah) (वसवः). Therefore, these are called Vasus.
----------The Brihadaranyaka Upanishad: 3: 9: 3
...

Katame vasava ityagnischa prithivi cha vaayuschantarikhang chadityascha dayuscha chandramascha naksatraani chaite vasava eteshu hidang sarvam hitamiti tasmad vasava eti ||
The Vasus transform themselves into the bodies and organs of all beings, which serve as the support of their work and its fruition, and also into their dwelling places. These Vasus enable beings to live (vaasayanti) (वासयन्ति).

Which are the Rudras (रुद्राः)?
The ten organs in the human body, with the mind as the eleventh. When they depart from this mortal body [when a man dies], they make [one's relatives] weep (rud) (रुद). Therefore, they are called Rudras (रुद्राः)
----------The Brihadaranyaka Upanishad: 3: 9: 4

The ten organs mentioned in the verse refer to the five sensory and the five motor organs

Which are the 12 Adityas?
"There are twelve months in a year. These are the Adityas because they move along carrying (aadadaanaah) (आददानाह) all this (life and all its phases) with them. Therefore, they are called Adityas"
----------The Brihadaranyaka Upanishad: 3: 9: 5
...

From the daily routine of a man to his longevity and the results of his works, everything is carried on by time (12 months, year by year).
