”deliverance of mind”. In the highest sense it signifies the fruition of Arahatship (s. ariya-puggala), and in particular, the concentration associated with it. It is often linked with the ”deliverance through wisdom” (pan~n~a^-vimutti, q.v.), e.g. in the ten powers of a Perfect One (s. dasa-bala). See vimokkha I.
It is also called ”unshakable deliverance of mind” (akuppa-c.); further ”boundless d. of m”. (appama^na-c.);”d. of m. from the conditions of existence, or signless d. of m.” (animitta^-c.);”d. of m. from the appendages” (a^kincan~n~a-c.), since that state of mind is free from the 3 bonds, conditions and appendants, i.e. from greed, hatred and ignorance; and since it is void thereof, it is called the ”void deliverance of mind” (sun~n~ata^-c.)
In a more restricted sense, ”boundless deliverance of mind” is a name for the 4 boundless states, i.e. loving-kindness, compassion, altruistic joy and equanimity (s. brahma-viha^ra);”d. of m. from the appendages” stands for the ”sphere of nothingness” (a^kin~can~n~a^yatana s. jha^na 7);”d. of mind from the conditions of existence”, for d. of mind due to non-attention to all conditions of existence;”void d. of m” for d. of m. due to contemplating voidness of self. For further details, s. M. 43.
