Ceto-Vimutti
ceto-vimutti：'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' （paññā-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-cetovimutti）； further 'boundless d．of m'．（appamāna-c.）； 'd．of m．from the conditions of existence，or signless d．of m.' （animittā-cetovimutti.）； 'd．of m．from the appendages' （ākincañña-cetovimutti），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' （suññatā-cetovimutti）
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-vihāra）； 'd．of m．from the appendages' stands for the 'sphere of nothingness' （ākiñcaññāyatana s．jhāna 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.
