How to reach the Certainty of Final Knowledge?

The Blessed Buddha once said:
Bhikkhus, there are these  4 Foundations of Awareness.
What four? The ever calmly self reminding awareness of:

1: Body is just a mass of disgusting impurities...
2: Feelings are only a repeating emotional noise...
3: Mind is simply a conditioned set of weird moods...
4: Phenomena are mentally baked & faked appearances...

While always acutely alert and clearly comprehending, thereby removing all lust,
desire, envy, jealousy, frustration, & any kind of discontent rooted in this world...
When, Bhikkhus, these 4 Foundations of Awareness have been developed, trained
& well established, one of two fruits may be expected: Either Final Knowledge in
this very life, or if there is residual clinging, the exalted state of Non-Return...!
