Many yoga practitioners suggest that if you choose to do only one yoga pose per day, then it should be the sun salutation, or Surya namaskar. The sun salutations actually occur in a series of poses that function to rejuvenate the circulatory system. The Sun Salutation B is a sequence of poses that goes beyond the poses completed in the Sun Salutation A.

(go-moo-KAHS-anna)
go = cow (Sanskrit go is a distant relative of the English word "cow")
mukha = face

Caution: Supta Virasana, the reclining variation of Virasana, is an intermediate pose. DO NOT perform this pose unless you can sit your buttocks relatively easily on the floor between your feet.

(soup-tah veer-AHS-anna)
supta = lying down, reclining
vira = man, hero, chief (compare Latin vir, “man,” the root of English words virile and virtue)

Vyasa, Patanjali's oldest extant commentator, mentions this pose, though he doesn't describe how to do it: "The curlew and other seats [asana] may be understood by actually seeing a curlew and the other animals seated" (Yoga Sutra 2.46).
