Our dear friend Tenzin Yignyen is on Facebook! He came to St. Lawrence three times in the past decade to create intricate Tibetan Buddhist sand mandalas. This reminds me of a time in Kathmandu when a few SLU faculty who were studying there were granted an audience with the Venerable Chokyi Nyima, and he stopped midway through his teaching to take a call on his cell phone.
Tenzin has been teaching at Hobart for several years, and every time I talk with Hobart students and faculty, they value his work very much there. Tenzin teaches courses on the meaning and signifiance of sand mandalas and other sacred arts.
