The primary function of the Lama

It is the Lama who gives us access to countless powerful methods of realisation.   
Lamas are teachers in a larger sense.  Lamas are not conditioned in any way by the style they adopt.  They may utilise many different styles according to the personality, capacity, and circumstances of those whom they teach.  Whatever method is implemented by the Lama, it transcends the function of the method as it is usually employed.  The Lama is in a completely different category.  So if we are to approach such a person; we need, at least, to be open to the unexpected.  We need to be prepared to question our range of perceptions and responses.  We need to be open to having our rationale actively challenged.
The Lama’s function is to mirror our intrinsic enlightenment.  The Lama shows us the nature of what we actually are.

The possibility of everything

"Once we perceive the small space of our habitual mind, we begin to long for the open vastness we have glimpsed in the eyes of the Lama. We begin to understand that in 'giving up' the dubious freedom of following our dualistic rationale, we are in fact losing nothing and gaining the possibility of everything."

The terrifyingly compassionate gamester

"The Lama is the ecstatic, wild and gentle figure who short-circuits your systems of self-referencing. The Lama is the only person in your life who cannot be manipulated. The Lama is the invasion of unpredictability you allow into your life, to enable you to cut through the convolutions of interminable psychological and emotional processes. The Lama is the terrifyingly compassionate gamester who reshuffles the deck of your carefully arranged rationale."
