In Hinduism, Surya (Devanagari: सूर्य, sūrya ("the Supreme Light"); Malay: Suria; Thai: พระอาทิตย์ Suraya, Suriya or Phra Athit) is the chief solar deity, one of the Adityas, son of Kasyapa and one of his wives, Aditi; of Indra; or of Dyaus Pitar (depending by the version). 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, which represent the seven colours of the rainbow or the seven chakras. He presides over Sunday.
