the escape from the forest of the aggregates, it is called nirvana. Vana means weaving and nir means negation. As there is no weaving, it is called nirvana. In a way that one with thread can easily be woven while one without that cannot be woven, in that way one with action (karma) and defilements (klesa) can easily be woven into life and death while an asaiksa who is without any action and defilements cannot be woven into life and death. That is why it is called nirvana. Vana means new birth and nir means negation. As there is no more new birth, it is called nirvana. Vana means bondage and nir means separation. As it is separation from bondage, it is called nirvana. Vana means all discomforts of life and death and nir means passing beyond. As it passes beyond all discomforts of life and death, it is called nirvana.According to Soonil Hwang, the Sarvastivada school held that there were two kinds of nirodha (extinction), extinction without knowledge (apratisamkhyanirodha) and extinction through knowledge (pratisamkhyanirodha), which is the equivalent of nirvana. In the Sarvastivada Abhidharma, extinction through knowledge was equivalent to nirvana, and was defined by its intrinsic nature (svabhava), ‘all extinction which is disjunction (visamyoga)’. This dharma is defined by the Abhidharmakosha as "a special understanding, the penetration (pratisamkhyana) of suffering and the other noble truths." Soonil explains the Sarvastivada view of nirvana as "the perpetual separation of an impure dharma from a series of aggregates through the antidote, ‘acquisition of disjunction’ (visamyogaprapti)." Because the Sarvastivadins held that all dharmas exist in the three times, they saw the destruction of defilements as impossible and thus "the elimination of a defilement is referred to as a ‘separation’ from the series." Soonil adds:That is to say, the acquisition of the defilement is negated, or technically ‘disjoined’ (visamyoga), through the power of knowledge that terminates the junction between that defilement and the series of aggregates. By reason of this separation, then, there arises ‘the acquisition of disjunction’ (visamyogaprapti) that serves as an antidote (pratipaksa), which henceforward prevents the junction between the defilement and this series. The Sarvastivadins also held that nirvana was a real existent (dravyasat) which perpetually protects a series of dharmas from defilements in the past, present and future. Their interpretation of nirvana became an issue of debate between them and the Sautrantika school. For the Sautrantikas, nirvana "was not
