大方廣佛華嚴經疏 3.21

3.21

三廣十義者，廣者多也，用多繁興，包無不盡故。則前十皆多，即明一遍一切名之為大，一攝一切名之為廣；亦可反此。此約離釋。若合釋方廣二字，亦有十義：一廣依義，謂言教繁廣，為生依故。二廣說義，宣說廣大甚深法故。三廣破義，破一切障無有餘故。四廣超義，無有諸法能比類故。五廣治義，具攝無邊對治之法，為能治故。六廣攝義，通攝無邊異類法故。七廣德義，具攝二嚴諸勝德故。八廣生義，能生無量廣大果海故。九廣絕義，非是心識稱量所能知故。十廣知義，具足種智，破邪見障無有餘。故此之十義，前四即《雜集》第十一中四義，後六即《入大乘論》第一中六義。

Third, the ten meanings of 'Expansive' (guang): 'Guang' means numerous; because functions are manifold and flourish, encompassing everything without exhaustion. Thus, the previous ten are all numerous; that is, clarifying that one pervading all is called 'great', and one subsuming all is called 'expansive'; it can also be the reverse. This is an explanation by way of separating them.
If one combines and explains the two characters 'Broad and Expansive' (fangguang; vaipulya), there are likewise ten meanings:
1. The meaning of broad reliance: the verbal teachings are manifold and extensive, serving as the reliance for sentient beings.
2. The meaning of broad proclamation: proclaiming and expounding vast and profound dharmas.
3. The meaning of broad destruction: destroying all obstructions without remainder.
4. The meaning of broad transcendence: no dharmas can be compared to it.
5. The meaning of broad remedy: fully subsuming boundless remedial dharmas to serve as the remedy.
6. The meaning of broad gathering: universally gathering boundless disparate dharmas.
7. The meaning of broad virtue: fully gathering the various superior virtues of the two adornments.
8. The meaning of broad production: capable of producing an ocean of immeasurable, vast fruits.
9. The meaning of broad severance: not something that can be known by the reckoning of ordinary mind and consciousness.
10. The meaning of broad knowing: fully equipped with the knowledge of all aspects (sarvākārajñatā), completely destroying the obstruction of wrong views without remainder.
Among these ten meanings, the first four are the four meanings in the eleventh fascicle of the Abhidharma-samuccaya-vyākhyā, and the latter six are the six meanings in the first fascicle of the Madhyāntavibhāga-bhāṣya.
