仁王護國般若波羅蜜多經疏 1.106

1.106

解云：讚自在行。言出入者，謂即滅定出入之心。言滅定者，明此菩薩無漏滅心寂然不起似涅槃故。如《瑜伽論》云「住滅定者，身語心行無不皆滅。」下廣明也。示現難量者，明此菩薩示現隨類隱顯難量。如《華嚴》云「此地菩薩，三昧智力以大方便，雖示現生死而恒住涅槃，雖眷屬圍繞而常樂遠離，雖以願力三界受生不為世法之所染污。」次第八地，其義者何？

Explanation: This praises the practice of mastery. 'Entering and emerging' refers to the mind that enters and emerges from the cessation absorption. 'Cessation absorption' explains that because this bodhisattva's uncontaminated mind of cessation is calm, quiescent, and does not arise, it resembles nirvāṇa. As the Yogācārabhūmi states: 'For one abiding in the cessation absorption, the activities of body, speech, and mind are all entirely ceased.' This will be elaborated below. 'Manifestations are difficult to fathom' explains that this bodhisattva's manifestations, adapting to various types [of beings] by concealing or revealing, are difficult to measure. As the Avataṃsaka says: 'The bodhisattva on this bhūmi, through the power of samādhi-cognition and great expedient means, although manifesting in saṃsāra, constantly abides in nirvāṇa; although surrounded by retinue, constantly delights in seclusion; although taking birth in the three realms by the power of vows, is not defiled by worldly dharmas.' Next, the eighth bhūmi: what is its meaning?
