Esoteric transmission (initiation) is a technique used by Vajrayana Buddhists to attain accelerated Buddhahood. This may alternatively be referred to as "pointing out", "pointing out transmission", or "introduction to the nature of mind". Senior Shambhala Buddhist teacher Jeremy Hayward describes this as "a direct pointing out of the nature of mind, that is mind's simplicity and universality—all appearances arise within the mind and in that sense there is nothing other than mind, yet mind itself is emptiness, openness beyond concept."
