" If 'the Buddha' is taken to signify the Ultimate, that which theistic mystics call the Godhead, it will be seen that these tremendous words ['I am the Buddha'] embody the very essence of mystical perception. One who understands them perceives himself to be both worshipper and worshipped, the individual and the universal, a being seeming insignificant but in truth divine! From this perception stem three obligations: to treat all beings, however outwardly repugnant, as embodiments of the sacred essence; to recognize all sounds, no matter how they offend the ear, as components of sacred sound; and to recollect that nowhere throughout the universe is other than Nirvana, however dense the dark clouds of illusion. Therefore, whatever befalls, the adept is clothed in divinity; with his eye of wisdom, he perceives the holiness of all beings, all sounds, all objects; and his heart of wisdom generates measureless compassion.
From the moment an aspirant begins seeking deliverance from within, abandons the dualism of worshipper and worshipped and recognizes the identity of 'self-power' and 'other-power' as sources of spiritual inspiration, the shakles of ego-consciousness are loosened; and as the power of the illusory ego wanes, the qualities of patience, forebearance and compassion blossom. Even so, a great danger inheres in the liberating concept 'I am the Buddha'; improperly understood, it leads to grossly irresponsible behaviour and to overweaning pride which, by inflating the ego instead of diminishing it, enmeshes the aspirant ever more tightly in delusion's bonds. Therefore this knowledge was formerly hidden from the profane and therefore the lamas teach skillful means for counteracting that grave hazard. Never must one reflect 'I am the Buddha' without recalling that, at the level of absolute truth, there is no such entity as 'I'! "
