Beth Dunn instructs the following:
Most forms of yoga in the West can be classified as Hatha Yoga. Hatha simply refers to the practice of physical yoga postures. The word “hatha” can mean “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. This is a wonderful class for beginners and also experienced practitioners. The more you practice, the deeper you can go into your postures or asanas.
