大方廣佛華嚴經疏 19.27

Second, from "Bodhisattva Dharmamati said" downward, he praises its profound and difficult-to-explain [nature]. The reason for praising it is that the essence of the Dharma is deep and vast, to remove doubt and inspire joy, and because below he resorts to speech to reveal and explain it, not yet exhausting its source. In this, the first phrase is general: to say "extremely profound" means that in terms of time it deeply penetrates the furthest boundary; in terms of virtue it deeply reaches the fruit of buddhahood; in terms of noumenon it deeply equals the dharmadhātu; in terms of practice it deeply embraces the ten thousand practices; being the utmost among depths, it is therefore called "extremely profound." Moreover, its numbers are vast and hard to measure, and its noumenon is abstruse and unfathomable; though deep, it would not be "extremely" so. Now, instantly the few is the many, instantly phenomena are noumenon, and the initial mind possesses the subsequent [stages]—this is called "extremely profound." The ten phrases below are specific; it is called "extremely profound" due to these ten meanings. Among them, the first four are distinguished in pairs of capable and targeted [aspects], with the former being capable and the latter being targeted in each case: 1. being free of speech, it is difficult to proclaim and display; 2. being signless, it transcends mind and consciousness; 3. it is not distinguishable by one's own power of eloquence; 4. it cannot be faithfully understood by inferior wisdom. The latter six pertain to both the capable and the targeted realization: 5. it cannot be realized by that which has attainment or by a single wisdom; 6. it cannot be practiced by initiating action or by a single practice; 7. the wisdom of sequential cultivation cannot penetrate it; 8 and 9. the wisdom of reflection cannot deliberate or assess it; 10. the wisdom of hearing cannot faithfully turn toward and enter it. These six are progressively inferior from front to back, skillfully revealing its profundity. The reason for extensively explaining that it is difficult is not only to establish the aforementioned extreme profundity, but precisely to admonish those of the present and future to cause them to believe.
