The 2 dimensions of
Nibbãna:
There is Nibbana here & now in this very life:
We call it 'sa-upadi-sesa-nibbana' i.e. Nibbana
with the substrates of becoming, still remaining:
Then there is final Nibbana, with no substrates
of being nor becoming left: an-upadi-sesa-nibbana:
Buddha explained it thus: The 2 aspects of Nibbana:
'This was said by the Blessed One:
"Bhikkhus, there are these two Nibbana-elements.
What are the two?
The Nibbana-element with residue left &
the Nibbana-element with no remains left.
"What, bhikkhus, is the Nibbana-element with residue left?
Here a bhikkhu is an arahat,
one whose mental fermentations is eliminated,
who have fulfilled the Noble life,
who has done all what was to be done,
who has laid down the burden, attained the goal,
who has destroyed the bondages of being,
who is completely released through final knowledge.
However, his five sense abilities remain unimpaired,
by which he still experiences what is agreeable and disagreeable,
and feels both pleasure and pain.
It is the extinction of attachment, aversion, and confusion in him,
that is called the Nibbana-element with residue left.
"Now what, bhikkhus, is the Nibbana-element with no residue remaining?
Here a bhikkhu is an arahat,
one whose mental fermentations is eliminated,
who have fulfilled the Noble life,
who has done all what was to be done,
who has laid down the burden, attained the goal,
who has destroyed the bondages of being,
who is completely released through final knowledge.
For him, here in this very life, all that is experienced,
not being delighted in, will grow cool right there & cease.
That, bhikkhus, is called the Nibbana-element with no residue left.
"These, bhikkhus, are the two Dimensions of Nibbana."
These two Nibbana-elements were thus made
known by the Seeing One, confident & detached:
The first is the element with substrates of being remaining,
realized here and now, but with re-becoming destroyed.
The other, having no residue left for the future,
is that wherein all modes of being utterly cease.
Having understood this unconstructed state,
released in mind, with the cord to becoming eliminated,
They attain to the sublime essence of all states.
Delighting in the ceasing & calming of craving,
those steady ones have left all being & becoming.'
