The Kalachakra initiation with His Holiness is not being sponsored by the Guhyasamaja Center. Please do not send requests for information to me because I will not be able to help you. I have several close friends who are members of the Capital Area Tibetan Association in Washington D.C. and who are actively engaged in the preparations for the initiation, so I can vouch for the accuracy of the information presented above. Also, the Kalachakra has been announced publicly at several events in D.C.
Please contact the event sponsors listed above for each event for more information. This information is provided as a courtesy to our fellow Dharma Centers so that we may help share these precious opportunities.
October 2010 update: volunteers at the Capital Area Tibet Association are still hard at work preparing for the event. Once the details have been ironed out, their website will be updated. In the meantime, you can prepare for the Kalachakra by reading some of the many excellent books about the Kalachakra tantra, engaging in purification practices, and practicing patience. Also, CATA will need volunteers, so you might think of how you can help support this holy event.
