It’s not 33 crore it’s 33 koti devta
33 Crore Gods’ is a completely misinterpreted fact due to wrong translation of Vedic Sanskrit by certain foreign 'scholars'.
The term ‘trayastrimsati koti’ mentioned in Atharva Veda, Yajur Veda, and Satapatha-brahmana, is rightly translated
as 33 Gods.
The number 33 comes from the number of Vedic gods explained by Yajnavalkya in Brhadaranyaka Upanishad – the eight Vasus, the eleven Rudras, the twelve Adityas, Indra and Prajapati. (Chapter I, hymn 9, verse 2).
According to Vedas there are 33 Gods/Devas.
These Gods are separated in the following pattern : 12 + 11 + 8 + 2.
12 is the number of Adityas, 11 are the number of Rudras, 8 is the number of Vasus, 1 is Prajapati, the Master of Gods, and 1 is the Supreme Ruler who is very powerful.
Names of all 33 Vedic deities:
12 Adityas (personified deities) correspond to the 12 Solar months and represent different attributes of social life. The Vedic sages especially venerated the Adityas and Vedas are full of hymns dedicated to Indra, Agni, Surya, Varun and the like. These are:
1. Indra/Shakra (eldest and the undoubted leader of other Adityas)
2. Ansh (due share),
3. Aryaman (nobility),
4. Bhaag (due inheritance),
5. Dhatri (ritual skill),
6. Tvashtar (skill in crafting),
7. Mitra (friendship),
8. Pushan/Ravi (prosperity),
9. Savitra/Parjanya
