Vimoksa

1) Vimokṣa (विमोक्ष, “liberation”) or Aṣṭavimokṣa refers to a set of “eight liberations” as defined in the Dharma-saṃgraha (section 59):

Vimoksha, : Vimokṣa

one having form perceives forms as empty,

not perceiving forms internally, one perceives forms externally as empty,

one perceives being resolved on beauty as empty,

one perceives the sphere of endless space as empty,

one perceives the sphere of endless consciousness as empty,

one perceives the sphere of nothingness as empty,

one perceives the sphere of neither-perception-nor-non-perception as empty,

one perceives the sphere of the cessation of perception and feeling as empty.

The Dharma-samgraha (Dharmasangraha) is an extensive glossary of Buddhist technical terms in Sanskrit (eg., vimokṣa). The work is attributed to Nagarjuna who lived around the 2nd century A.D.

2) Vimokṣa (विमोक्ष, “liberation”) or Trivimokṣa refers to the “three liberations” as defined in the Dharma-saṃgraha (section 73):

śūnyata (empty), animitta (signless), apraṇihita (desireless).
