19.107

「於五取蘊至名為我慢」者，釋第四慢。於五取蘊執我、我所，此是我見。或緣我起慢、或恃我起慢、或由我起慢，故名我慢。

"Toward the five clinging-aggregates [...] is called the conceit of 'I'"—this explains the fourth conceit. Grasping at self and what belongs to self in the five clinging-aggregates (upādānaskandha) is the view of self (ātmadṛṣṭi). Conceit arising either with the self as its object, or relying on the self, or originating from the self, is therefore called the conceit of 'I' (asmimāna).
