Introduction to Hatha Yoga
Most forms of yoga in the West can be classified as Hatha Yoga. Hatha simply refers to the practice of physical yoga postures, meaning your Ashtanga, vinyasa, Iyengar and Power Yoga classes are all Hatha Yoga. The word “hatha” can be translated two ways: as “willful” or “forceful,” or the yoga of activity, and as “sun” (ha) and “moon” (tha), the yoga of balance. Hatha practices are designed to align and calm your body, mind, and spirit in preparation for meditation.
