Comm. NT: 1.
Āhārepaṭikkūlabhāvanāvaṇṇanā

The word ‘perception’ (saññā) is used for the dhamma with the characteristic of perceiving (sañjānana), as in the case of ‘perception of visible objects,’ ‘perception of sound,’ etc.; and it is used for insight, as in the case of ‘perception of impermanence,’ ‘perception of suffering,’ etc.; and it is used for serenity, as in the passage, ‘Perception of the bloated and perception of visible objects, have these one meaning or different meanings, Sopāka?’ (Source untraced. Cf. III.111), and so on.
Here, however, it should be understood as the preliminary work for serenity;
for it is the apprehending of the repulsive aspect in nutriment, or the access jhāna produced by means of that, that is intended here by, ‘perception of repulsiveness in nutriment’

Nyanamoli thera	1. Now comes the description of the development of the perception of repulsiveness in nutriment, which was listed as the “one perception”1 next to the immaterial states (III.105).
