大方廣佛華嚴經疏 13.4

13.4

Three, in querying and explaining, it queries the word 'inconceivable' above. Below, the explanation says, 'The capacities able to evoke [a response] are boundlessly distinct, and the Tathāgata's universal response pervades the dharmadhātu'—broadly inconceivable. The concluding text below fully reveals this. Furthermore, preaching the Dharma according to what is suitable, the import is inconceivable. Again, 'equaling the dharmadhātu': adducing a single preaching of Dharma equals the remaining multiple gates, and the gates cannot be exhausted; their measure equals the dharmadhātu, so the Dharma gates are inconceivable.
