is constructed and therefore impermanent, the fetters are destroyed, arahantship is attained, and nibbāna is realized. Visuddhimagga The Theravada exegete Buddhaghosa says, in his Visuddhimagga:It is called nibbana (extinction) because it has gone away from (nikkhanta), has escaped from (nissata), is dissociated from, craving, which has acquired in common usage the name ‘fastening (vana)’ because, by ensuring successive becoming, craving serves as a joining together, a binding together, a lacing together, of the four kinds of generation, five destinies, seven stations of consciousness and nine abodes of being.According to Buddhaghosa, nibbāna is achieved after a long process of committed application to the path of purification (Pali: Vissudhimagga). The Buddha explained that the disciplined way of life he recommended to his students (dhamma-vinaya) is a gradual training extending often over a number of years. To be committed to this path already requires that a seed of wisdom is present in the individual. This wisdom becomes manifest in the experience of awakening (bodhi). Attaining nibbāna, in either the current or some future birth, depends on effort, and is not pre-determined. In the Visuddhimagga, chapter I.v.6, Buddhaghosa identifies various options within the Pali canon for pursuing a path to nirvana. According to Gombrich, this proliferation of possible paths to liberation reflects later doctrinal developments, and a growing emphasis on insight as the main liberative means, instead of the practice of dhyana. The mind of the Arahant is nibbāna A related idea, which finds no explicit support in the Pali Canon without interpretation, and is the product of contemporary Theravada practice tradition, despite its absence in the Theravada commentaries and Abhidhamma, is that the mind of the arahant is itself nibbāna. The Canon does not support the identification of the "luminous mind" with nirvanic consciousness, though it plays a role in the realization of nirvāṇa. Upon the destruction of the fetters, according to one scholar, "the shining nibbanic consciousness flashes out" of it, "being without object or support, so transcending all limitations." Modern Theravada views K.N. Jayatilleke, a modern Sri Lankan Buddhist philosopher, holds that nirvana must be understood by a careful study of the Pali texts. Jayatilleke argues that the Pali works show that nirvana means 'extinction' as well as 'the highest positive experience of happiness'. Jayatilleke writes that despite the definition of nirvana as 'extinction', this does not mean that it is a kind of annihilation or a state of dormant nonentity,
