仁王護國般若經疏 2.33

2.33

「三慧」者，次歎慧，謂聞、思、修。初是乾慧地，次是四善根，苦忍已上名修慧。「十六諦」者，次歎觀門，如前說云云。「四諦」者，次歎諦門，亦如前說云云。「四三二一品觀」者，次歎四門，即四觀忍也。從下舉之：煖第四、頂第三、忍第二、世第一法第一。四即四善根，三即除煖位，二除煖頂，一除前三也。又四即四果，三即三果，二即二果，一即初果。此非歎意，今取前釋。

As for "three wisdoms," next it praises wisdom, meaning [wisdom from] hearing, contemplation, and cultivation. The first is the stage of dry wisdom; the next is the four wholesome roots; and from the patience of suffering upward it is named the wisdom of cultivation. "Sixteen truths": next it praises the contemplations, as explained before, and so forth. "Four truths": next it praises the gateways of the truths, also as explained before, and so forth. "Contemplation of the four, three, two, and one grades": next it praises the four gateways, namely the four patiences of contemplation. Adducing them from the bottom: heat is fourth, summit is third, patience is second, and highest mundane dharma is first. Four refers to the four wholesome roots; three eliminates the rank of heat; two eliminates heat and summit; and one eliminates the prior three. Moreover, four refers to the four fruits; three refers to the three fruits; two refers to the two fruits; and one refers to the first fruit. This is not the intended praise; now we take the former explanation.
