Aryaman (Sanskrit: अर्यमन्, pronounced as "aryaman"; nominative singular is aryama) is one of the early Vedic Hindu deities. His name signifies "close friend", "play-fellow" or "companion". He is the third son of Aditi, the mother of the Adityas and is depicted as the mid-morning sun disk
In the Rig Veda Aryaman is described as the protector of mares, and the Milky Way (aryamṇáḥ pánthāḥ) is said to be his path. Aryaman is commonly invoked together with Varuna-Mitra, Bhaga, Bṛhaspati, and other Adityas and Asuras. According to Griffith, the Rig Veda also suggests that Aryaman is a supreme deity alongside Mitra and Varuna. According to the Rig Veda, Indra who is traditionally considered the most important deity in the Rig Veda is asked to obtain boons and gifts from Aryaman.
The Hindu marriage oaths are administered with an invocation to Aryaman being the witness to the event.
