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. To enter into vajra commitment is to leap from the perfect precipice. To find yourself in the radiant space of this choiceless choice is the very heart of Tantra. To leap open-eyed into the shining emptiness of the Lama’s wisdom display and to experience the ecstatic impact of each dynamic gesture of the Lama’s method display is the essential luminosity and power of the path.
