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, voice 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. For more detail, please see the new Dance of the Vajra website.
The Portland Dzogchen Community is currently raising funds to purchase a Vajra Dance Mandala. The cost is about $1400. We have collected about $500 so far. Once we get the mandala, we will begin practice and will invite an authorized Vajra Dance teacher to come to our community. There are DVDs and practice books available which we will use as well once we get the mandala.
Please consider a donation for the purchase of the mandala.
