The Ashtanga Primary Series, known in Sanskrit as Yoga Chikitsa or “yoga therapy,” is far more than a demanding physical workout. Its sequence is a meticulously crafted tool for healing, beginning with the most tangible aspect of our being: the physical body. According to traditional yogic philosophy, to address the inner world, one must first understand the outer vessel.

The series’ emphasis on forward folds is not arbitrary. Contemporary disease, the teachings suggest, often stems from diet and digestion. By compressing the digestive organs and stretching the posterior spine, the postures work to purify and strengthen the internal systems. This therapeutic focus is grounded in the alignment of the thoracic spine, the body’s primary curve. Throughout the standing poses and the Primary Series itself—from the demanding Utthita Hasta Padangustasana (Extended Hand to Big Toe Pose) to the deep release of Supta Kurmasana (Sleeping Tortoise Pose)—practitioners are instructed to tuck the rib cage, maintaining this structural integrity. This foundational work prepares the body for the more intense spinal extensions of the Intermediate Series, proving that true spiritual progress always begins with a stable and purified foundation.
