八、解了證得。補闕云：四諦名證得，上論已明，即婆沙中七種善法也，加重觀集謂業為受集，加此一種故成八也。觀察自性者，觀受體苦。觀現法轉因緣者，謂轉為受集集諦。觀現法轉滅因緣者，此觀受滅。當來轉因緣者，觀業為未來受集，轉之與業並能生受名轉因緣。觀彼二轉滅因緣者，道諦能滅前二種觀。轉因緣因緣者，觀受愛味，復與轉業作其因緣，是故名轉因緣因緣。觀還因緣因緣者，還是滅諦，前說道諦滅轉及業與滅為因。今重觀受以為過患，能滅愛味助道顯滅，名觀察因緣因緣。及觀察還者，重觀滅諦。

Eighth, understanding realization. The Supplement says: The four truths are called realization, as explained in the treatise above; they are the seven wholesome dharmas in the Vibhāṣā, with the addition of contemplating origin again—namely, karma as the origin of feeling; adding this one makes eight. 'Contemplating the intrinsic nature' is contemplating the substance of feeling as suffering. 'Contemplating the conditions for arising in the present life' refers to arising as the origin of feeling, the truth of origin. 'Contemplating the conditions for the cessation of arising in the present life' contemplates the cessation of feeling. 'The conditions for arising in the future' contemplates karma as the origin of future feeling; arising and karma are both capable of generating feeling, hence called 'the conditions for arising'. 'Contemplating the conditions for the cessation of both kinds of arising' is the truth of the path, which can cease the preceding two kinds of contemplation. 'The conditions for the conditions of arising' contemplates the gratification of feeling, which further serves as a condition for the karma that causes arising; therefore it is called 'the conditions for the conditions of arising'. 'Contemplating the conditions for the conditions of cessation': cessation is the truth of cessation; the previous explanation said that the truth of the path ceases arising and karma, serving as the cause for cessation. Now, contemplating feeling again as a fault can cease gratification and assist the path in revealing cessation; this is called 'contemplating the conditions for the conditions'. 'And contemplating cessation' is contemplating the truth of cessation again.
