仁王經疏 3.341

3.341

釋曰：第五、立果也。謂十三法師中住第十法師位，於四果中第四果也。梵天位者，梵者淨也，已住清淨行位故。

Explanation: The fifth establishes the fruition. It means that among the thirteen dharma masters, one abides in the position of the tenth dharma master; among the four fruitions, it is the fourth fruition. As for the 'position of Brahmā', brahmā means pure; because one already abides in the stage of pure conduct.
