Ashtanga Yoga is Hatha Yoga
If classical yoga gives priority to breathing exercises, the development of flexibility and relaxation, then Ashtanga Yoga forms the strength of mind and body. In order to achieve the main goal - samadhi (complete balance, spiritual perfection) - eight difficult stages will have to be completed.
Ashtanga Yoga is an eight-step Path to the ultimate Goal - Samadhi (the highest spiritual perfection). This system was proposed several centuries ago by the Indian Rishi Patanjali.
