The essential condition for giving important teaching is a permission from one's own Guru
The reason for me to teach the Longchen Nyingthik Ngondro is my karma. I have this great karma and aspiration to have the chance to practice Longchen Nyingthik. And not only that but also my great teachers have given me the permission to teach these profound teachings. It is one of the important conditions for a dharma teacher to teach a instructions, important instruction is to have the permit from one’s Guru.
It’s a very common for all Buddhist teachings and especially in Vajrayana teachings, that being a Vajrayana master one must have received the words from the guru saying “you do this”, to permit or to give the authority to a student of the Guru, saying: “From now, you’re going to teach this to keep the lineage.”
I actually have permission from all of my teachers. My teachers were very important teachers at the time, like Lama Sang, and Dodrupchen and some other lamas, maybe you don’t know or maybe you have heard. There is one, a very important Dzongchen master named Tampi Wangchu. And also there is another one [named] Pema Yanzep, who passed away last year. And Tampi Wangchu passed away 4 or 5 years ago. They specifically requested me to teach Longchen Nyingthik and the teachings on the profound, the great Dzongchen teachings. These teachers that I just mentioned are not ordinary teachers but they were really important teachers, very important teachers in this century. I don’t think there will be more important or more authentic than these will appear, very difficult to appear, to have something like that. And then they did not tell me this privately, but they told me this in the public, in front of thousands of people, thousands of monks in Tibet. And it’s very necessary to have a lineage, and to have a great teacher, and to have the permission from the teacher to teach to others – the lineage and the master – to be a Vajra master. So that’s ones of the very important factors is to be a teacher. This is very important condition, for me, personally, to be a teacher of Longchen Nyingthik.
