In 1980, in California, Lama Yeshe gave a commentary to the Avalokiteshvara (Chenrezig) yoga method. This video is Lama's introduction to that teaching series and constitutes a wonderful explanation of the fundamentals of tantric practice.
"In order to practice tantric yoga we need a foundation – the preliminaries. First of all, in order to practice tantric yoga, we need to receive an empowerment, or initiation. There are degrees of initiation, but we do need initiation. In order to receive an initiation, we need a certain extent of realization of the three principal paths to enlightenment, which are the wisdom of shunyata, bodhichitta and renunciation." – Lama Thubten Yeshe.
