大方廣佛華嚴經疏 14.3

14.3

There are also four gates to explain this chapter. First, regarding the purpose of its placement, there are general and specific [meanings]. 'General' means: the preceding three chapters have already answered the ten lines on the basis from which understanding is generated; from here below, it directly answers the principal understanding of cause and fruition, hence it follows next. Within the cause that generates understanding, it first answers the ten abodes, for the abodes gather faith to be completed; about to answer what is completed, it first distinguishes that which can complete it. Furthermore, it directly answers the ten faiths, which is why the subsequent three chapters follow. As for the 'specific': the three chapters clarify that faith has understanding, practice, and virtue; understanding serves as the root of the [other] two, so this chapter comes first.
