Buddhist-Meditation-Systematic-and-Practical

v. Not uncertain. This has double meaning: there is no
definite "thing" called "Nirvana" but still Truth itself
appears as a certainty.
vi. Not new, not old. Nirvana is already here and is
neither made a new by something nor created in the
past.
vii. No obstacle. Nirvana may also have this meaning,
for one who attains it has no obstacle to liberation.
c. There are five definitions according to the
Abhidharma Vibhasa Sastra:
i. It is said there that "Nir" means "go out," and "vana''
means "forest." Its attainment is thus to go out from the
forest of sorrows.
ii. It may mean "no weaving," as in the first definition in
the list from the Great Nirvana Sutra.
iii. Another derivation gives "no rebirth" as opposed to
continuing in the cycle of births through the six worlds.
iv. Nirvana as "no bondage": the world of
birth-and-death is bound by ignorance, and so Nirvana
may signify renunciation of bondage.
v. "Going across the river of birth-and-death" is the last
meaning given.
