The Life Vase Cave is considered an epitome of sanctity. It is believed that Guru Rinpoche met Buddha Amitayus here, from whom he received teachings and empowerment. The cave houses the Life Vase, a treasure that contains a self-arisen treasure letter symbolized by the sacred symbol ཨ (Ah). A tap near the cave entrance channels Tshe Chu, the holy water of longevity, which is always flowing.
