Rūpakhandha

Abhidhammapiṭaka · Vibhaṅga · Vol. 35 · Section 42

[42] The form aggregate (rūpakkhandha) by way of the tenfold classification: the eye faculty (cakkhundriya) … the life faculty (jīvitindriya); form that is not a faculty (indriya) — there is that with impingement (sappaṭigha), there is that without impingement (appaṭigha). Thus the form aggregate is tenfold.
