| frame | The [[Twelve deeds of the supreme nirmanakaya Buddha]] Nirmanakaya (Skt. nirmāṇakāya; Tib. སྤྲུལ་སྐུ་, tulku, Wyl. sprul sku), or 'the dimension of ceaseless manifestation'<ref>Sogyal Rinpoche, The Tibetan Book of Living and Dying, page 347.</ref>, is defined as a rupakaya or 'form kaya | body' that arises from the ruling condition of the sambhogakaya and appears as the tamer of various beings, both pure and impure.

Or, as Sogyal Rinpoche writes: :In Tibetan Buddhism the nirmanakaya is envisioned as the manifestation of enlightenment, in an infinite variety of forms and ways, in the physical world. It is traditionally defined in three ways. :*One is the manifestation of a completely realized Buddha, such as Gautama Siddhartha, who is born into the world and teaches in it; :*another is a seemingly ordinary being who is blessed with a special capacity to benefit others: a tulku; and :*the third is actually a being through whom some degree of enlightenment works to benefit and inspire others through various arts, crafts, and sciences. In their case this enlightened impulse is, as Kalu Rinpoche<ref>Kalu Rinpoche, The Dharma (Albany: State Univ. of New York Press, 1986), page 59.</ref> says, “a spontaneous expression, just as light radiates spontaneously from the sun without the sun issuing directives or giving any conscious thought to the matter. The sun is, and it radiates.”<ref>Sogyal Ripoche, The Tibetan Book of Living and Dying, page 355.</ref>
