Explanation: In correctly contemplating the five aggregates (pañcaskandha) through contemplative practice (vipaśyanā-caryā), one must not take the aggregate of form (rūpa) as self, nor may one take the aggregate of form as belonging to self. Both self and the self's possessions are self-view (ātma-dṛṣṭi), and both must be eliminated; the mind should hold no notion of the aggregate of form as "I" nor of the aggregate of form as "mine." In daily life, one will then not engage, for the sake of the aggregate of form, in dharmas that should not be engaged in—for example, craving the various feelings of the physical body, or giving rise to anger when the body cannot obtain what it likes. Unwholesome karma all the more should not be committed, such as killing, stealing, sexual misconduct, and so forth.

It is because there is a self that there is what belongs to self; if there is no self, then there is nothing that is the self's. Both "self" and "the self's" are unreal and unreliable, not to be depended upon; when both are extinguished, liberation is attained.
