Nirvana is not a place, a state, or a heaven, it is not a
conditional phenomena where laws of physics apply. But neither is
it a post-mortem thing - nirvana can be attained in this body, in
this life.
Nirvana is simply the termination, the cessation, of passion,
aggression and delusion.
"And this, monks, is the noble truth of the cessation of stress:
the remainderless fading & cessation, renunciation,
relinquishment, release, & letting go of that very craving." ~
Dhammacakkappavattana Sutta
Pleasure is the
binding force in the world.
Rolling thought processes are its ever changing base.
With the complete eradication of craving,
The state called nibbana is attained.
-- Samyutta-nikaya I, Nal. 37, PTS 39; Suttanipata verse 134,
Nal. 436, PTS 202.
"This is peace, this is exquisite — the resolution of all
fabrications, the relinquishment of all acquisitions, the ending of
craving; dispassion; cessation; Nibbana."
