extinction: s. nirodha; - of craving: taṇhakkhaya  (q.v.).

Buddhist Dictionary, Manual of Buddhist Terms and Doctrines, by NYANATILOKA MAHATHERA

Extinction. Western writers have generally associated extinction of being with the concept of nirvana, the afterlife corresponding to the Christian goal of heaven expressed in the Beatific Vision. This is incorrect and due to a misunderstanding. What characterizes the nirvanic concept is the notion of the extinguishing of desire, of the world of maya (illusion) with all the passions of anger and avarice that attend it and that contain the roots of all evil and suffering. Existence as encumbered by such impediments may be said to be extinguished, but the extinction consists in the purification of the essential nature of the self from the encumbrances that seem to the ordinary person to be inseparable from it. These encumbrances are what flow like muddy streams into an ocean of forgetfulness. So much are they associated with life in the mind of the common man that they are taken to be life itself and, since they are annihilated, life is erroneously perceived as being annihilated, but that is not as the enlightened person sees nirvanic bliss.

Extinction  滅度  It means having put the Two Obstacles, i.e. the obstacle of afflictions and the obstacle of what is known, to an end. It also means that the beings have transcended the Two Deaths, i.e. glare-sectioned birth and death and changed birth and death.
