Hatha Yoga is the branch of Yoga that deals with the perfect balance of body and mind. It is a system of mental and physical training with prescribed asanas(postures), breathing exercises, and relaxation.
The asanas were originally devised to prepare the practitioner for higher Yogic teachings, which is why Hatha Yoga has unique features. These features help the practitioner who so desires to pursue the path of spiritual development. For those who do not wish to pursue this path, Hatha Yoga can help tremendously to achieve physical, mental, and emotional well-being.
The various asanas combine the contraction, stretching, and twisting of the body along with breathing and concentration to obtain maximum benefits. The effects of the asanas has been widely studied and are known to be of tremendous value in therapeutic use. They not only make the body suppler and condition the muscles but they also tone up the internal organs and glands enabling the practitioner to achieve radiant health and vitality.
When you sit in posture for a few minutes it creates within you a specific mental state because the physical state is closely connected to the mental state of a person. These yoga postures are very important especially for the beginners to change their mental states and prepare them for higher mental and spiritual practices.
