the Five Grades of Mental Purity:
Initially the Noble Learner
temporarily disables the mental hindrances
and bindings by "Substitution by the Opposite" using insight.
Lust is thus
temporarily substituted by disgust, anger by friendliness, restlessness
by calm, laziness by
energy, and doubt is substituted by certainty.
Later the Noble Learner temporarily
overcomes the mental hindrances
and bindings by "Suppression" by entering one-pointed
Jhāna absorption of
concentration, which is unmixed, unpolluted, and untainted by hindrances.
Later the Noble
Learner permanently eliminates another fraction of the
hindrances and bindings by "Cutting Off" at reaching path-moment
Stream-entry, Once-Returner, Non-Returner and Arahant (Magga) state.
Later the Noble Learner permanently eliminates the remaining fraction
of hindrances by effortless
"Calming" at reaching the
the Stream-entry, Once-Returner, Non-Returner and Arahant (Phala) state.
Finally the Noble Learned
irreversibly leaves behind all mental hindrances
and bindings by
"Escape" into the unconditioned
of Nibbāna, without remaining traces of either clinging, or other fuel...

Suppression => Cut Off => Calming => Escape!
