仁王護國般若波羅蜜多經疏 2.96

2.96

解曰：無色二字，如前已解。言四空者，一空無邊處、二識無邊處、三無所有處、四非想非非想處，定義如前，唯無尋伺有勝淨定之所起業。如《俱舍》云「修加行時思無邊空，離第四禪，生立空無邊處。依此分近諸無間道，厭下有漏，麁苦障三隨一行相，諸解脫道欣空根本，靜妙離三隨一行相，得生彼四蘊成身，依命根眾同分壽二萬劫。識等三處，准此應知，壽四萬劫、六八萬劫，定漸勝故。」從此第三結業果空。於中分二：且初第一明業果空。

Exposition: The two characters "formless" are as explained before. The "four formless attainments" are: 1. the sphere of infinite space, 2. the sphere of infinite consciousness, 3. the sphere of nothingness, and 4. the sphere of neither-perception-nor-non-perception. The definition of concentration is as before; lacking vitarka and vicāra, they have the karmas aroused by superior, pure concentration. As the Abhidharmakośa says: "When cultivating preparatory practice, one contemplates infinite space, detaches from the fourth dhyāna, and arises to establish the sphere of infinite space. Relying on this neighboring threshold path of uninterruptedness, one reviles the lower defiled state, contemplating any one aspect among coarseness, suffering, or obstruction; in the paths of liberation, one delights in the fundamental space, contemplating any one aspect among calm, subtle, or detachment, thereby attaining birth in those four skandhas to form a body, with a lifespan of twenty thousand kalpas based on the life-faculty and nikāya-sabhāga. The three spheres beginning with consciousness should be understood accordingly, with lifespans of forty thousand kalpas, and sixty and eighty thousand kalpas, because their concentrations are progressively superior." Next is the third: concluding that karma and retribution are empty. In this there are two: first, clarifying that karma and retribution are empty.
