Hello, Could you have some information of these terms in details?
samayika vimutti - here samayika means ‘temporary’ i.e. not permanent and vimutti means ‘liberation’ or ‘release’ or ‘deliverance’ from suffering and the cycle of birth and death. it is said to be achieved by developing jhanas through concentration meditation (samatha). In samayika vimutti, one’s mind is temporarily freed from certain defilements such as sensual lust (raga) and ill will (dosa). but it is still temporary because defilements are suppressed and not eradicated completely. meaning once the samayika vimutti ends, those defilements can re-emerge.
nirodha samapatti - it is the cessation of perception (sanna) and feeling (vedana) and is said to be achieved by only anagamis and arahants after highest jhanas. i think it is achieved after going beyond the 31st realm i.e. beyond the sphere of neither perception nor non-perception. and only ariyas (noble beings) can go beyond 31 realms…so makes sense that it is achievable by only anagamis/arahants.
arahatta phala samadhi - i think you are referring to arahatta phala (fruition of arahatship) here. regardless, i think it refers to samadhi in which there is experience of fruition of arahatship.
the main difference as i read, is that nirodha samapatti and arahatta phala samadhi are accessible to ariya/noble beings (who have realized 4 noble truths) whereas samayika vimutti is when one who has not realized 4 noble truths, enters jhanas.
others might respond better i feel.
Hello, thank you for the response and details.
