涅槃經遊意 1.137

1.137

解云：涅槃非物非不物相得，更問道何物耶？無物而物，而物所謂正道。故肇師云：「涅槃者，名為道也。涅槃無名，強為立名，名為涅槃。」但下文明名有二種：一因緣名，二無因緣名。因緣名如舍利弗也；無因緣者如坻羅婆夷，實不食油強名食油。涅槃亦爾，無有因緣強名涅槃也。

Explanation: If nirvāṇa is comprehended as neither a thing nor not a thing, why ask further what kind of thing it is? Being no thing, it is a thing; and this thing is what is called the correct path. Therefore Master Zhao says: 'Nirvāṇa is named the path. Nirvāṇa is nameless; one forcibly establishes a name for it, naming it nirvāṇa.' However, a passage below clarifies that there are two kinds of names: first, conditioned names; second, unconditioned names. Conditioned names are like 'Śāriputra'; unconditioned names are like 'Tailapāyikā' (oil-drinker), who in reality does not drink oil, but is forcibly named 'oil-drinker'. Nirvāṇa is likewise thus: having no conditioning cause, it is forcibly named nirvāṇa.
