Surya

Surya is the god of sun, light and day. He is the husband of Sanjna and Chaaya Devi. He is also the father of Yama, Yamuna and Manu. He is the son of Aditi and Kashyapa. He is one of the main gods since we all live because of the sun. He is also the teacher of Hanuman.

History
The oldest surviving Vedic hymns, such as the hymn 1.115 of the Rigveda, mention Sūrya with particular reverence for the "rising sun” and its symbolism as dispeller of darkness, one who empowers knowledge, the good and all life. However, the usage is context specific. In some hymns, the word Surya simply means sun as an inanimate object, a stone or a gem in the sky (Rigvedic hymns 5.47, 6.51 and 7.63); while in others it refers to a personified deity.

Surya's origin differs heavily in the Rigveda, with him being stated to been born, risen, or established by a number of deities, including the Ādityas, Aditi, Dyaush, Mitra-Varuna, Agni, Indra, Soma, Indra-Soma, Indra-Varuna, Indra-Vishnu, Purusha, Dhatri, the Angirases, and the gods in general. The Atharvaveda also mentions that Surya originated from Vritra.
