大方廣佛華嚴經疏 51.40

51.40

Seventh, from 'expounding ten kinds of Dharma' onward, there are two gates clarifying the practice in the stage of non-retrogression. Therein, the first is its own station, and the latter is superior progress. In the former, because one can expound the profound and broad Dharma, upon hearing it expounded, the mind does not retrogress. Among the ten, expounding the nature of karma, etc., accomplishes the powers of the Tathāgata, and explaining in accord with the meaning causes bodhisattvas not to retrogress. Chapter 28 of the *Nirvāṇa [Sūtra]* extensively clarifies the marks of retrogression and non-retrogression. The rest of the text can be understood. The twenty kinds of upholding: 'upholding' means receiving, upholding, and practicing, not merely proclaiming it with one's mouth. The ten phrases can be understood.
