Internal (ajjhattikānaṃ): in this connection,
On what follows, cf. Paṭis-a I 33f. and As 46; also Ud-a 374. they are internal (ajjhattikāni), since they occur making the self their locus,
Attānaṃ adhikāraṃ katvā, or "point of reference" -- cf. As-mṭ 47; attānaṃ adhikicca uddissa pavattā ajjhattā. as if with the implication that they will proceed taking [that occurring]
Paṭis-a and As read evaṃ pavattamānā for Ee evaṃ. in that way to be the self.
Herein: that which is internal is fourfold, viz. that which is internal by way of pasturage, that which is internal within one's own, that which is internal by way of objective field, and that which is internal per se.
As to these, that spoken of in "Internally delighted, concentrated" (S V 263) and so on -- this is said to be that which is internal by way of pasturage;
that handed down as "Bringing serenity internally" (S II 211) and so forth -- this is said to be that which is internal within one's own;
That handed down as follows, viz. "Without paying attention to any sign, he dwells entered upon emptiness internally" (M I 111) -- this is said to be that which is internal by way of objective field;
[whilst] that spoken of, in this connection, viz. "Internal states; external states" (Dhs 2; §§ 1044ff.; 1418) -- this is said to be that which is internal per se.
In the present case, too, it is this same that is implied; therefore, they are simply internally internal.
Reading ajjhattāni yeva with Ce Be Se for Ee ajjhattani yeva.
Or alternatively,
Atha vā those that are internal, such as the eye and so on, take place within those that are internal, as they do in "Internal states; external states" (Dhs 5; §§ 1207f.) and so forth in the sense already stted -- for those [six] internal [bases].
