In the Dzogchen Teaching sound and movement are very important because they are the means to integrate oneself into the state of contemplation. The Vajra Dance is principally a practice to harmonize the energy of the individual. If one has a more profound knowledge of the meaning of the Dance, it becomes a method for integrating the three existences of body, energy and mind into the knowledge of the state of contemplation. This integration is one of the most important aims of a Dzogchen practitioner. The Vajra Dance is practiced on a Mandala which represents the correspondence between the internal dimension of the individual and the outer dimension of the world.
