大方廣佛華嚴經疏 8.21

8.21

四建立者，為十地中對治十障、證十真如，故但有十。為對六蔽，漸修佛法、漸熟有情，故但說六。六中，前三增上生道，感大財體及眷屬故；後三決定勝道，能伏煩惱、成熟有情及佛法故。又前三饒益有情，施財、不惱、忍彼惱故；後三對治煩惱，勤修加行永伏永滅故。又由前三故不住涅槃、由後三故不住生死，能為無住涅槃資糧；後唯四者，助六令滿，方便助前三、願助精進、力助靜慮、智助般若，如《深密》說。

4. Establishing them: to counteract the ten obstructions and realize the ten tathatās within the ten stages, there are only ten. To counteract the six coverings, gradually cultivate the Buddhadharma, and gradually mature sentient beings, only six are spoken of. Among the six, the first three belong to the path of elevated rebirth, because they induce the reward of great wealth, bodily form, and retinue; the latter three belong to the path of definitive excellence, because they are able to subdue afflictions and bring sentient beings and the Buddhadharma to maturity. Moreover, the first three benefit sentient beings, because one gives wealth, does not harm them, and endures their harm; the latter three counteract afflictions, because by diligently cultivating preparatory application one permanently subdues and eradicates them. Furthermore, due to the first three one does not abide in nirvāṇa, and due to the latter three one does not abide in saṃsāra, thus serving as provisions for non-abiding nirvāṇa. That there are only four later ones is because they assist the six in reaching completion: skillful means assists the first three; vows assist vigor; powers assist meditation; and wisdom assists prajñā, as stated in the Saṃdhinirmocana.
