仁王護國般若波羅蜜多經疏 2.223

2.223

解曰：四地菩薩往億佛剎、五地百億、六地千億。不可說者，顯其多也，遍往此等諸剎土中現通化利。從此第四明無生忍。文三如前，且初第一標忍辯位。

Commentary: A bodhisattva of the fourth bhūmi goes to one hundred million buddha-lands, of the fifth bhūmi to ten billion, and of the sixth bhūmi to one trillion. 'Ineffable' shows their great number; one goes everywhere to these lands, manifesting supernormal powers to transform and benefit. Hereafter, the fourth [section] explains non-arising kṣānti. The text has three parts as before; first, the first designates the kṣānti and distinguishes the stages.
