The Sanctuary for Yoga, in Medford, will host a three-day Ashtanga Immersion workshop from 7:30 to 9 p.m., January 9, 11 a.m. to 1 p.m., January 10, and noon to 2 p.m., January 11. Facilitator Sarah LaFleur will introduce participants to this ancient system of yoga based on the three points of focus of bandhas (energy locks), ujayai (victorious breath) and drishti (gaze).

Each day is comprised of discussion, demonstration and practice. Topics include Stoking the Fire: Trishtana & Surya Namaskar; Mortar & Sand: Six Fundamental Asanas; and Root Down to Rise Up: Seated Series. The workshop is appropriate for all levels, from beginners to advanced yogis looking for an extra nudge in their practice.

“Ashtanga is the backbone of any vinyasa practice,” says Tricia Heiser, registered yoga teacher and owner of The Sanctuary for Yoga. “When taught in the Mysore style, students practice at their own pace and receive personalized attention, resulting in more dynamic growth and greater understanding.”

Cost: $75. Location: 43 S. Main St. For more information or to register (required), visit TheSanctuaryForYoga.com.
