Comm. NT: 81.
Kamādivinicchayakathāvaṇṇanā

When all formed dhammas are grouped together according to similarity, they naturally fall into five aggregates.
Herein, it is the items that are the same owing to the sameness consisting respectively in ‘molesting,’ etc., that are to be understood as ‘similar.’
Among them, those that are strong in the volition whose nature is accumulating with the function of forming the formed, are called the formations aggregate.
And the others, that is, contact, etc., which are devoid of the distinguishing characteristics of ‘being molested,’ etc., may also be so regarded under the generality of forming the formed. But the similarities consisting in touching are not describable separately by the word ‘aggregate,’ and so that is why no aggregates of contact, etc., have been stated by the Perfect One who knows the similarities of dhammas.
‘Bhikkhus, whatever ascetics or brahmans there are who are asserters of eternity and declare the self and the world to be eternal, all do so depending and relying on these same five aggregates or on one or other of them’ (cf. S IV 46), and so on.
