Eunice is an ashtanga yoga practitioner. She describes the surya namaskar sequence that she demonstrates in the video as “form, connected with breath in the same sequence every time you do it”.
There are many variations on sun salutations or surya namaskars as a sequence of asanas (poses) in yoga. But the first systematic presentation of surya namaskar only appeared 90 years ago in Aundh (now part of the Indian state of Maharashtra), in 1938 in ‘The Ten-Point Way to Health: surya namaskars’ written by Pratinidhi Pant, the Rajah of Aundh.
The Rajah didn’t claim to invent surya namaskar: “What we give here is in fundamentals the age-old method of performing surya namaskars, and the one followed by our revered father the late Rajah of Aundh. For 55 years he did these.” He simply, “developed and changed it in accordance with modern science… and experiment by ourselves in person” (Pant, 1938).
Sun salutations were indeed an ancient tradition, originally thought to have been purely incantations to the rising sun. The poses themselves are similar to traditional martial arts exercises called dands and jors. The Rajah, who was also a bodybuilder, notes that the traditional ‘pahilwan’ or wrestler would have used such exercises to build strength, but excessive overuse was not healthy.
