仁王護國般若波羅蜜多經疏 2.513

2.513

解曰：諸法相待者，此總標也。待者藉待，謂蘊處界諸有為法闕緣不起，相待藉也。所謂色界眼界眼識界者，明行相也。根境識三若不同世及互闕者，識定不生。境正現前、根正發識，識正了境，必相藉待方照解故。乃至已下舉後例中，皆具三和明待藉也。猶如電光者，結不久也，假不實故，即滅無故。從此第二明形待假。

The commentary explains: 'All phenomena are mutually relative' is the general heading. 'Relative' means dependent and reliant; that is to say, all conditioned dharmas among the aggregates, sense fields, and realms do not arise if conditions are lacking, but are mutually relative and reliant. 'Namely: the form realm, the eye realm, and the eye-consciousness realm' explains their operative aspects. If the three—sense faculty, object, and consciousness—are not in the same temporal moment or if any one is missing, consciousness definitely does not arise. Only when the object is directly present, the faculty directly produces consciousness, and consciousness directly discerns the object, must they rely on one another before illumination and understanding can occur. 'Up to' and what follows cites the subsequent to serve as a parallel for the intermediate; all possess the harmony of the three, illustrating reliance and relativity. 'Just like a flash of lightning' concludes that they do not last long, because as designations they are unreal, immediately ceasing and becoming nonexistent. Hereafter, the second part explains the designation of formal relativity.
