（十四）「身表」──是由于从心等起的风界所转起的往（还屈伸）等，[PTS 448] 以俱生色身的支持保持和动的缘的变化行相。有表示自己的意志的味。为身的动转之因是现起。从心等起的风界是足处。

Ñ(XIV,61): 14. Bodily intimation is the mode (conformation) and the alteration (deformation) in the consciousness-originated air element that causes the occurrence of moving forward, etc., which mode and alteration are a condition for the stiffening, upholding, and moving of the conascent material body. [448] Its function is to display intention. It is manifested as the cause of bodily excitement. Its proximate cause is the consciousness-originated air element.

Sā panesā kāyavipphandanena adhippāyaviññāpanahetuttā, sayañca tena kāyavipphandanasaṅkhātena kāyena viññeyyattā ‘‘kāyaviññattī’’ti vuccati.

而此（身表）因为由于身的动转而表明意志之故，并且它自己亦称为身动转，因为由身而表（意志）之故，是名身表。

Ñ: But it is called 'bodily intimation' (kāyaviññatti) because it is the cause of the intimating (viññāpana) of intention by means of bodily excitement, and because it is itself intimatable through the body, in other words, through that bodily excitement.

Tāya ca pana calitehi cittajarūpehi abhisambandhānaṃ utujādīnampi calanato abhikkamādayo pavattantīti veditabbā.

当知往（还屈伸）等的转起，是因为身表的动及时节生等（的诸色）与心生的诸色亦结合而动之故。

Ñ: Moving forward, etc., should be understood to occur owing to the movement of the [kinds of matter] that are temperature-born, etc., which are interlocked with the consciousness-born kinds moved by that [intimation]. (See Dhs. §636.)
