仁王經疏 1.121

1.121

言八解脫者，第四、解脫德。一內有色觀諸色、二內無色觀外色、三淨解脫具足住、四入空無邊處、五入無邊識處、六入無所有處、七入非想非非想處、八入想受滅解脫。具說如彼，略所如上。然此八種，諸說不同。薩婆多宗，如《婆沙》說，初三無貪，對治貪故，兼所相應隨轉。若欲界者，四蘊為性；若色界者，即具五蘊；四無色處解脫，四蘊為性；第八解脫，是不相應行蘊所攝。依經部宗，自在兩說。一云：皆用智慧為體。一云：前七是慧；第八解脫，有餘無餘二種涅槃以為自性。今依大乘，前三，四蘊五蘊以為自性；次四，四蘊；第八解脫，非色非心不相應行以為自性。

The phrase "eight liberations" refers to the fourth virtue, that of liberation: (1) internally having form, one observes forms; (2) internally lacking form, one observes external forms; (3) the pure liberation, fully dwelling [therein]; (4) entering the base of infinite space; (5) entering the base of infinite consciousness; (6) entering the base of nothingness; (7) entering the base of neither-perception-nor-non-perception; (8) entering the liberation of the cessation of perception and feeling. The detailed account is as given there, and the summary is as given above. However, with respect to these eight kinds, various explanations differ. According to the Sarvāstivāda school, as stated in the Vibhāṣā, the first three are non-greed, because they counteract greed, along with their associated and accompanying [dharmas]. If belonging to the desire realm, they have the four aggregates as their nature; if belonging to the form realm, they possess the five aggregates; the four formless-base liberations have the four aggregates as their nature; the eighth liberation is subsumed under the non-associated aggregate of conditioning factors. According to the Sautrāntika school, master [Śrīlāta] has two explanations: one says that all take wisdom as their essence; another says that the first seven are wisdom, while the eighth liberation takes the two kinds of nirvāṇa—with residue and without residue—as its intrinsic nature. Now according to the Mahāyāna, the first three take the four aggregates and five aggregates as their intrinsic nature; the next four, the four aggregates; and the eighth liberation takes the non-associated conditioning factors that are neither form nor mind as its intrinsic nature.
