The two have been friends since 1991. Later that year, Lama Tharchin’s Vajrayana Foundation purchased the land for the Pema Osel Ling retreat center near Santa Cruz, California. Ngak’chang Rinpoche spent three months on the site when it was first purchased, helping transform it into a Vajrayana venue. He worked on—among other things—the hat for the colossal Padmasambhava statue. Since then, Ngak’chang Rinpoche has often taught at Pema Osel Ling.
Lama Tharchin Rinpoche and Ngak’chang Rinpoche renewed their friendship in February, 2011. Due to conflicting teaching schedules, they had not been able to meet for five years. Ngak’chang Rinpoche (with some close students) spent a day at Pema Osel Ling and had much to discuss with Lama Tharchin.
