大方廣佛華嚴經隨疏演義鈔 76.9

76.9

疏「二以於身對上日月為光影」者，日月喻為菩薩悲智，身喻物機，日照發影以喻現身等。而言「映日」等者，等取經上月字及燈燭故。疏「弄影多端故喻於諸識」者，上約別喻菩薩現身，此約通喻一切諸識。動身俯仰即是弄影，形端影正、形曲影斜，故云「多端」。以況八識依身有異，亦喻七識依第八識對境差別。上皆《攝論》意。叡公云：「光不照處，謂之為影。不照慧明，生死長永，捨遠夷途，而行榛梗。若能悟之，狂滅自醒。」

Regarding the commentary's "Second, matching the body against the sun and moon above constitutes the light-and-shadow [metaphor]": the sun and moon illustrate the bodhisattva's compassion and wisdom, the body illustrates the receptivity of beings, and the sun shining to cast a shadow illustrates the manifestation of bodies and so forth. As for the expression "reflected by the sun, etc.," the "etc." includes the words 'moon' and 'lamps and candles' found in the sūtra. Regarding the commentary's "Manipulating shadows in diverse ways therefore illustrates the various consciousnesses": above, it specifically illustrated the bodhisattva manifesting bodies; here, it generally illustrates all consciousnesses. Moving the body and bending or looking up is precisely manipulating the shadow: when the form is upright the shadow is straight, when the form is crooked the shadow is oblique; hence it is called "diverse ways." This illustrates how the eight consciousnesses differ based on the body, and also illustrates the seven consciousnesses confronting different sensory realms based on the eighth consciousness. The above are all the intent of the Mahāyānasaṃgraha. Master Sengrui said: "Where light does not illuminate is called a shadow. When not illuminated by the light of wisdom, saṃsāra is long and eternal; abandoning the distant, level path, one walks among thorns and briars. If one can awaken to this, madness is extinguished and one awakens naturally."
