2.229

其動發思發身、語者多為近因，為因引起身、語二故，故名等起。能起名起；第二念後心、心所等但名剎那，剎那剎那自相引起。近因起者，名之為轉，依彼現、種立表、無表；剎那等起，名為隨轉，隨前轉故。不依現、種立無表等，以非決定是善、惡性起身、語故，由有隨轉業起分明，故立有也。

The motive intention that initiates body and speech is mostly the proximate cause; because it acts as the cause inducing body and speech, it is called 'concurrent origination'. That which can initiate is called 'origination'. Mind and mental factors after the second moment are merely called 'momentary', each moment inducing itself. That which arises from proximate causes is called 'transforming'; on the basis of its manifest [activity] and seeds, manifest and unmanifest [actions] are established. Momentary concurrent origination is called 'following along', because it follows along with the preceding transformation. Unmanifest [action] and so forth are not established on the basis of its manifest [activity] and seeds, because it does not initiate body and speech with a determinately wholesome or unwholesome nature; however, because the subsequent action arises clearly through [this] following along, its existence is established.
