Surya, or Lord Surya, is sometimes described as the god of health. Depictions of Surya often show him riding a chariot, which is harnessed by seven horses. These horses represent the seven chakras.
Hindus and yogis revere Surya as being the creator of life on Earth and may regard him as the spiritual heart of the world. Thus, the sun salutations of Surya Namaskara acknowledge and revere this divinity. They are, in essence, a moving prayer to the sun.
Sri K. Pattabhi Jois, who popularized the Ashtanga yoga method, is reported as saying that no yoga practice is complete unless it includes sun worship. He advocated praying to Surya before performing Surya Namaskara in order to focus the mind and set one's intention on achieving unity with God.
