Hatha comes from the words 'ha', meaning 'sun' and 'tha', which 'moon' means.
This form is often seen as the branch of yoga that brings unity of opposites in the body system, the positive (sun) - and negative (moon) currents.
The physical body is aligned by means of physical exercises, called asana's. Each exercise has its own specific purpose and picks up a disharmony to. At Hatha yoga is not to jump the meaning as in sport quickly in and out of an attitude, but mentally going into an attitude, the attitude to observe and slowly go back.
In asanas no violence is used against the body. Share your experience and knowledge of Hatha yoga.
