traditions is described as the realization of sunyata (emptiness or nothingness). Madhyamika Buddhist texts call this as the middle point of all dualities (Middle Way), where all subject-object discrimination and polarities disappear, there is no conventional reality, and the only ultimate reality of emptiness is all that remains. Synonyms and metaphors A flame which goes out due to lack of fuel A commonly used metaphor for nirvana is that of a flame which goes out due to lack of fuel:Just as an oil-lamp burns because of oil and wick, but when the oil and wick are exhausted, and no others are supplied, it goes out through lack of fuel (anaharo nibbayati), so the [enlightened] monk … knows that after the break-up of his body, when further life is exhausted, all feelings which are rejoiced in here will become cool.Collins argues that the Buddhist view of awakening reverses the Vedic view and its metaphors. While in Vedic religion, the fire is seen as a metaphor for the good and for life, Buddhist thought uses the metaphor of fire for the three poisons and for suffering. This can be seen in the Adittapariyaya Sutta commonly called "the fire sermon" as well as in other similar early Buddhist texts. The fire sermon describes the end of the "fires" with a refrain which is used throughout the early texts to describe nibbana:Disenchanted, he becomes dispassionate. Through dispassion, he is fully released. With full release, there is the knowledge, 'Fully released.' He discerns that 'Birth is ended, the holy life fulfilled, the task done. There is nothing further for this world. An end state, where many adverse aspects of experience have ceased In the Dhammacakkapavattanasutta, the third noble truth of cessation (associated with nirvana) is defined as: "the fading away without remainder and cessation of that same craving, giving it up, relinquishing it, letting it go, not clinging to it." Steven Collins lists some examples of synonyms used throughout the Pali texts for Nirvana:the end, (the place, state) without corruptions, the truth, the further (shore), the subtle, very hard to see, without decay, firm, not liable to dissolution, incomparable, without differentiation, peaceful, deathless, excellent, auspicious, rest, the destruction of craving, marvellous, without affliction, whose nature is to be free from affliction, nibbana [presumably here in one or more creative etymology,= e.g., non-forest], without trouble, dispassion, purity, freedom, without attachment, the island, shelter (cave), protection, refuge,
