Surya Namaskara
Surya Namaskara, or the Sun Salutation, which is very commonly practiced in most forms of yoga, originally evolved as a type of worship of Surya, the Vedic solar deity. Surya, the Hindu solar deity by concentrating on the Sun, for vitalization. The physical aspect of the practice 'links together' (Sanskrit: vinyāsa) twelve asanas in a dynamically expressed series. A full round of Surya namaskara is considered to be two sets of the twelve poses, with a change in the second set where the opposing leg is moved first. The asanas included in the sun salutation differ from tradition to tradition.
