Contemplating Transience reduces false perception of
permanence:
The Blessed
Buddha once said:
Aniccānupassanam bhāvento
niccasaññam pajahati...
When developing the contemplation of
Impermanence
(Anicca),
one overcomes perception of permanence...

The anytime, everywhere, & for everybody
directly observable facts are:
All states will
pass...
All things will vanish...
All formations are
unstable...
All mountains crumble
into nothing...
All memories are lost like tears in rain...
Nothing remains
static without change...
All buildings & homes
collapse into dust...
All phenomena are of a nature to breakup...
All moments
momentarily cease never to return...
All Universes implodes into pointless singularity...
All phenomena are momentary & thus temporary...
All bodies grow old, decrepit, fall & finally rotten...
All worldly happiness & pleasure changes & are lost...
All beings grow old, sick, ugly, dement, smelling & die...
All forms of form will decay, deteriorate & fall apart...
All constructions - physical as mental - arises & ceases...
There is no lasting permanence anywhere except
Nibbāna...
