Hatha yoga is a technique that uses physical poses and breathing exercises to achieve balance between the body and mind. The primary elements are poses (asanas) and breath control (pranayama), but there are also eight limbs that encompass ethical practices, concentration, meditation, and enlightenment. Some key poses discussed are mountain pose (tadasana), tree pose (vrikshasana), standing forward bend (uttanasana), downward facing dog (adho mukha svanasana), bridge pose (setu bandhasana), and locust pose (salabhasana). Each pose is said to stimulate different chakras and provide physical, mental and spiritual benefits.
