Upādāna

This hierarchy of clinging types is represented diagrammatically to the right.

Thus, based on Buddhaghosa's analysis, clinging is more fundamentally an erroneous core belief (self-doctrine clinging) than a habitualized affective experience (sense-pleasure clinging).

"Craving is the aspiring to an object that one has not yet reached, like a thief's stretching out his hand in the dark; clinging is the grasping of an object that one has reached, like the thief's grasping his objective.... [T]hey are the roots of the suffering due to seeking and guarding."

Thus, for instance, when the Buddha talks about the "aggregates of clinging," he is referring to our grasping and guarding physical, mental and conscious experiences that we falsely believe we are or possess.
