"The Lama is crucial in terms of offering a reflection of the path. In Vajrayana, the Lama becomes the path. He or she becomes the path through manifesting the yidam. He or she becomes the path through manifesting the nature of the teachings in terms of the kyil’khor of interaction – the interaction between the students, the interaction between the person and their world, and how the Lama comments on that and interacts with the nature of what is taking place."
