The term Surya also refers to the Sun, in general. Surya has hair and arms of gold. He is said to drive through the heaven in his triumphal chariot harnessed by seven horses or one horse with seven heads,[1] which represent the seven colours of the rainbow or the seven chakras. He presides over Sunday.

In Hindu religious literature, Surya is notably mentioned as the visible form of God that one can see every day. Furthermore, Shaivites and Vaishnavas often regard Surya as an aspect of Shiva and Vishnu, respectively. For example, the sun is called Surya Narayana by Vaishnavas. In Shaivite theology, Surya is said to be one of eight forms of Shiva, named the Astamurti.

His other names include Vishnu, Vivasvān (Sanskrit root: Vivasvat, विवस्वत्) Ravi (lit. "the Fire Bird"[2]), Aditya (lit. the son of Aditi),[4] Pusha (the best Purifier), Divakar (the maker of the day), Savita (the vivifier), Arka अर्क (the ray), Mitra (friend),[4] Bhanu (light), Bhaskar (maker of Light), and Grahapati (the Lord of Grahas).[5]
