維摩經略疏 6.142

6.142

「文殊至一床」，二、明文殊入室見相知表。「見其室空無諸所有」者，即知表諸佛土空，必欲開發扶成佛國之教。見其以疾獨寢一床，即知表三德解脫，必欲顯發扶成佛說不思議解脫之教。故《大論》云「智人能知智，如蛇知蛇足。」

“Mañjuśrī arrived at the single couch” is second, clarifying Mañjuśrī's entering the room, seeing the signs, and understanding what they signify. “Seeing that his room was empty and devoid of anything” means he knew it signified that all buddha-lands are empty, definitely intending to disclose, support, and fulfill the teaching on buddha-lands. Seeing him lying alone on a single couch on account of illness, he knew it signified the liberations of the three virtues, definitely intending to reveal, support, and fulfill the Buddha's teaching of the inconceivable liberation. Thus the Dàzhìdù lùn says: “A wise person understands wisdom, just as a snake knows a snake's feet.”
