Explicitly from the Veds.

Some are mentioning they never believed in 33M devte as facets of creation, and that 33 (Tridasha) are mentioned in Veds.  Depending on what you read, various internet sites with Hindu authors have a varying take on the final number, but nowhere have I seen that they believe in one supreme entity, unless Brahman is encompassing all and the Gods/Devte are seen as his manifestations.

I would say bhagvad gita would be their main scriptures besides vedas, upanisads and vedant.
