Comm. NT: 2. Tīraṇa could also be rendered by “judging.” On specific and general characteristics Vism-mhṭ says:
Sammasanañāṇakathāvaṇṇanā
Hardness, touching, etc., as the respective characteristics of earth, contact, etc., which are observable at all three instants [of arising, presence and dissolution], are apprehended by their being established as the respective individual essences of definite materialness. But it is not so with the characteristics of impermanence, and so on.
These are apprehended as though they were attributive material instances because they have to be apprehended under the respective headings of dissolution and rise and fall, of oppression, and of insusceptibility to the exercise of mastery
See Ch. XXI, note 3.
The “planes” given here in §4 are not quite the same as described in XXII.107.
