The Adityas are divine intelligence. They supervise and maintain the cosmic evolutionary process. In the full Indian system there are 12 Adityas, 8 Vasus, 11 Rudras, and 2 Ashwinis which together make up the root number 33. Simplified versions have 2, 3, 6, 7 or 8 Adityas.
The 12 adityas by association lead to the notion of chakra 12 in music being Aditya.
The sun is also described as the Aditya and has 3 wives (+ 1 Shadow Wife: Chaya):
