Hatha Yoga

Hatha Yoga has grown in popularity in the West as a form of exercise that develops strength, flexibility, bodily relaxation, and mental concentration. Its true object, however, is to awaken the dormant energy (shakti) of Shiva that animates the subtle body but is concealed behind the gross human frame.

The subtle anatomy containing it is usually described as a series of lotiform chakras (“wheels”) rising from the anal or genital area to the top of the head. Through the forceful suppression of physical and mental activity, the female shakti is enabled to rise along the chakras and unite with the male Shiva in the uppermost chakra, a union indistinguishable from enlightenment and even immortality.

Hatha yoga is a branch of yoga. The word haṭha literally means “force” and thus alludes to a system of physical techniques. In the 20th century, hatha yoga, particularly asanas (the physical postures), became popular throughout the world as a form of physical exercise, and is now colloquially termed as simply ” yoga”.
