Surya Namaskar or ‘Sun Salutation’

Surya Namaskara (Sanskrit: सूर्य नमस्कार) also known in English as Sun Salutation (lit. “salute to the sun”) is a common sequence of asanas. Its origins lie in India where they worship Surya, the Hindu solar deity. This sequence of movements and asanas can be practised on varying levels of awareness, ranging from that of physical exercise in various styles, to a complete sadhana which incorporates asana, pranayama, mantra and chakra meditation. It is often the beginning vinyasa within a longer yoga series. Sūrya Namaskāra may also refer to other styles of “Salutations to the Sun”.

Incidentally the translator of the ancient Sritattvanidhi was also responsible for arranging for Sri. T. Krishnamacharya to teach yoga at Yogaśālā in Mysore sometime around 1930. Sri. T. Krishnamacharya’s teachings are largely responsible for the modern version of Sūrya Namaskāra as seen in modern day Ashtanga Vinyasa Yoga and the Visesha Vinyasa Sun Salutation subroutine from Vinyasa Krama Yoga, as well as a host of other popular forms of yoga.

K. Pattabhi Jois claims to have taught exactly as he had learned from Krishnamacharya, though other than personal testimony, there seems to be no other evidence as to the precise content of Krishnamacharya’s teachings. While Krishnamacharya’s specific sources for his yoga teachings are unclear, it is said that he learned from Sri Ramamohana Brahmachari in the Himilayan Mountains beginning in 1916 however, the source of his teaching (at the Mysore Yogashala or otherwise) is not otherwise documented. Krishnamacharya’s son attests to his father having developed some of his teachings himself. There is the possibility that he may have been influenced by the Mysore Palace Gymnastics Tradition.
