The Tibetan tantric yoga is a practice that has been done by Indian and Tibetan yogis for centuries, and is not like yoga usually practiced in the West. It is a practice of rLung (psychic wind) and exercise of the mind purely based on spiritual development, which was laid down by the tantric tradition of master Pundit Naropa and later masters. The exercice removes the negative energies from the channels and chakras by physical positions and movements which harmonize wind and mind and release inner stress and tension. Dedicated and genuine pratitioners may tame the wind, develop spiritual experience, and become able to control the mind and emotion. The life-long exercice with proper motivation and correct view can lead to the pure state of awakened Buddhahood. Generally the yoga technique basically helps stimulate the channels and chakras, and purifies the body/mind and promote the health.
