Deity

sngags kyi ngo bo - identity of mantra. [detailed expl., The Light of Wisdom, Vol. 2, page 198] Moreover: In general, the identity of mantra is not regarded as only an uttered sound or word, but rather it is never the case that the deity, its mantra and the state of samadhi are anything other than a single nature. The deity's nature of unchanging awareness is therefore what appears in the form of the seed syllable that is its spiritual life-force. The mantras are taught to be consonants that are the identity of the great bliss of means, and the vowels that are the identity of the knowledge of emptiness. [DILGO KHYENTSE] [RY]

sngags kyi yan lag lnga (sngags kyi de kho na nyid) - Five aspects of Mantra: The thatness of deity (lha'i de kho na nyid) is the relative bodhichitta. The thatness of self (bdag gi kho na nyid) is the mandala of body. The thatness of guhya-mantra (gsang sngags kyi kho na nyid) is the placement of the seed syllable and the mantra chain in the center of the heart (heart center) (snying thig). The thatness of recitation (bzlas brjod kyi kho na nyid) is the repetition of the root mantra, essence mantra and quintessence mantra. The thatness of emanation and absorption ('phro 'du'i kho na nyid) is the emanating and reabsorbing of light rays from the seed syllable. (RY)
