Sogyal Rinpoche (http://en.wikipedia.org/wiki/Sogyal_Rinpoche) is a Tibetan Dzogchen Lama of the Nyingma tradition, who is extremely popular in the West, among non-Asian Buddhists as well as among the spiritual minded in general, and especially the young ones. He is one of the three most popular and well known Buddhist icons which are revered in the West: His Holiness the Dalai Lama, Thich Nhat Hanh and Sogyal Rinpoche.
Listen to Sogyal Rinpoche's "sermons" and you'll see why.

* To explain the title of this post: Sogyal Rinpoche is, unfortunately, not my teacher. "Words of My Perfect Teacher" is the title of a well-known (among Buddhists) book by Patrul Rinpoche (http://tinyurl.com/yt9h9m) and also a documentary film by Lesley Ann Patten (http://tinyurl.com/29wpul)
