Buddha once said: Dukkhānupassanam bhāvento
sukhasaññam pajahati...
When developing the contemplation of
Suffering (dukkha),
one gradually overcomes the false perception of pleasure...
The Blessed
Buddha once convinced a disputant by this cut-2-the-bone explanation:
Friend Aggivessana,
what do you think,
is any material form, is any feeling, is any perception,
is any mental construction, and is any consciousness,
always permanent or
always impermanent?
Venerable Gotama, they are all ever
impermanent...
If these things are
impermanent, are they then pleasurable or painful?
Venerable Gotama, then they are all painful...
Aggivessana, what do you think,
When one searches for
what is suffering, clings to what is suffering,
resorts to what is suffering, holds on to what is suffering and regards
what is suffering as: "This is mine, this I am, this is my self..."
can one then ever understand suffering or be freed from all suffering?
How could one ever Master Gotama, no never Master
Gotama...
