We are providing these practice-texts here in hopes of making it easier for practitioners with the necessary background to access such materials. Although most of these practices come from the Drikung Kagyu Lineage, not all of them are. The offerings here are texts used by Drikung Dharmakirti Circle - a small community of Drikung Kagyu practitioners who operate Urban Dharma North Carolina in Asheville, North Carolina.
As for the issue of who is "authorized" or "qualified" to practice or access the materials made available here, we are in no position to tell anyone if they are "qualified" or "unqualified" to engage in these practices. Please consult your own spiritual guides if you are unsure.
Whenever we update any of these texts, an email will automatically go out to anyone who has purchased any text with a new link to the updated version.
