仁王般若經疏 2.61

2.61

慧光開士下，二行偈四句頌上九地。初句三禪王者，明利他人。第二句一時者，明利他身。第三句歎無功用行。第四句歎無功用智教，故云一念了。

From "The great master of Wisdom Light" down, two verse lines of four phrases praise the ninth ground. The first phrase, "king of the third dhyāna," clarifies the person who benefits others. The second phrase, "simultaneously," clarifies the body that benefits others. The third phrase praises effortless practice. The fourth phrase praises effortless wisdom and teaching; hence it says "comprehending in a single thought-moment."
