Recently Lama Zopa Rinpoche visited Dehra Dun India where he met with His Holiness Sakya Trizin, and received many empowerments and transmissions.
The lineage of these practices had completely died out in the Gelug tradition, so Lama Zopa Rinpoche has been working on having these empowerments happen since 1990 and requested and arranged for these transmissions to happen in order to bring them back into the Gelug tradition, thus helping to preserve the Mahayana tradition in general.
This is a wonderful example of H.H. Sakya Trizin and Lama Zopa Rinpoche fostering a truly non-sectarian attitude for the benefit of the Dharma.
