5.867

述曰：釋名也。一切心可得，即遍行五。不問何心，但起必有故。緣別別境而得生者，五別境也，此意即顯遍性、地等，唯緣別別境界方生，故餘不例，如五十五說。於四事中生五別境，如下當知。或俱、不俱，別事生故。

The Commentary states: This is explaining the names. 'Obtainable in all minds' refers to the five omnipresent factors. No matter what citta it is, whenever it arises they must be present. 'Arising only by taking distinct and individual objects as their support' refers to the five object-contingent factors; this meaning reveals that they are omnipresent across natures, stages, and so forth, but arise only by taking distinct and individual objects as their support, and therefore the rest do not follow this rule, as explained in fascicle 55. Among four matters the five object-contingent arise, as will be known below. They arise either simultaneously or not simultaneously with respect to distinct matters.
