言初門說未至地位者，謂離生喜樂滋潤其身是，周遍以下為後門是根本位，初唯潤其意俱，後方遍悅身等故，後勝前劣，既言喜樂明亦有樂。今取顯喜以隱顯相通舉唯取顯者，以理論之，此地亦有樂，以悅根故名樂也。

As for the statement that the initial gateway describes the status of the unarrived stage: this refers to "the joy and pleasure born of separation moistening one's body." From "pervasive" downward is the subsequent gateway, which is the foundational state. The former only moistens what is associated with the mind, whereas only later does it pervasively gladden the body and so forth; hence the latter is superior and the former is inferior. Since it speaks of "joy and pleasure," it is clear that pleasure is also present. Now, presenting the manifest joy while the implicit and manifest mutually connect means that merely presenting the manifest is because, reasoned theoretically, this stage also has pleasure; because it gladdens the faculties, it is called pleasure.
