大方廣圓覺修多羅了義經略疏 1.659

1.659

此同《法華》，欲令眾生開示悟入。以開攝示，以悟攝入，以開示約能化、悟入約所化故。約今經者，此後佛答，全用先所顯示如來淨圓覺心為本，以觀人、法二空，及滅影像無邊虛空，覺所顯發，覺圓明故，顯心清淨乃至等同諸佛，即是普令開悟也。

This is identical to the Lotus Sūtra's wish to lead sentient beings to open, reveal, awaken to, and enter [buddha-knowledge]. 'Opening' subsumes 'revealing', and 'awakening to' subsumes 'entering', because opening and revealing pertain to the one who transforms, while awakening to and entering pertain to those who are transformed. In terms of the present sūtra, the Buddha's subsequent answer takes entirely as its basis the previously revealed pure, perfectly enlightened mind of the Tathāgata, in order to contemplate the two emptinesses of person and phenomena, as well as the extinction of images into boundless empty space, which is manifested by enlightenment; because enlightenment is perfectly luminous, revealing the purity of the mind up to being equal to all buddhas is precisely universally bringing them to awaken.
