About Trul khor

Tsa lung Trul khor, known in short as Trul khor "magical instrument" or "magic circle" is a Vajrayana discipline which includes pranayama and body postures (asanas). From the perspective of Dzogchen, the mind is merely vāyu "breath" in the body. Thus working with vāyu and the body is paramount, while meditation on the other hand is considered contrived and conceptual.
