Disillusion =>
Ceasing => Bliss => NibbAna!

The Blessed Buddha once
said:
Bhikkhus, when the
Four
Foundations of Awareness are developed and
cultivated well, then they lead to revulsion, to disillusion, to ceasing,
to peace, to direct knowledge, to enlightenment, to Nibbāna
itself...
What four? When an honest and devoted Bhikkhu keenly considers:
1: The Body
just as frame, and neither as lasting, mine, nor attractive...
2: The Feeling as reaction, and neither as pleasant, my self, or stable...
3: The Mind merely as mood and neither as fine, I or Ego, or special...
4: Phenomena as states,
and neither as nice, permanent, or substantial...
When the
Four Foundations
of Awareness are developed and trained well,
then they lead to revulsion, to disillusion, to ceasing, to
stilling, to peace,
to direct knowledge, to enlightenment, and even to Nibbāna!
Brief Comments:
Disillusion
means comprehending impermanence, suffering, and no-self.
Ceasing means
the gradual fading away of greed, aversion
and ignorance.
Peace means absence of urge, craving, frustration and stirring activity.
Bliss means absence of pain
and sadness, and presence of Happiness.
Nibbāna means
signless, not created, not conditioned,
and not changing!
