The Dzogchen Ponlop Rinpoche, holder of the Karma Kagyu and Nyingma lineages, in a 2008 talk delivered to LGBT Dharma practitioners at the Shambhala Meditation Center of New York, stressed that for vajrayana lay practitioners, homosexual relationships are no better or worse than heterosexual relationships and that only unhealthy relationships, in general, are to be avoided. Both the Nalandabodhi sangha, which was founded by The Dzogchen Ponlop Rinpoche, and the Shambhala sanghas founded by Chögyam Trungpa Rinpoche have stated that they are welcoming of all sexual orientations. The Shambhala Meditation Center of New York hosts a weekly practice group, Queer Dharma, specifically catering to the needs of the LGBTQ Buddhist community. According to the Danish Karma Kagyu Lama Ole Nydahl, Buddha saw homosexuality as circumstances making life more difficult, but also explained the reason for homosexuality could be aversion against the opposite sex in a former life. Nydahl says however that sexual orientation is not really important in order to practice Buddhism.
