[503] "But, friend, how many conditions are there for the attainment of the release of mind (cetovimutti) that is neither painful nor pleasant?"
"Friend, there are four conditions for the attainment of the release of mind that is neither painful nor pleasant. Here, friend, with the abandoning of pleasure and the abandoning of pain, and with the previous disappearance of joy and grief, a bhikkhu enters and dwells in the fourth jhāna, which is neither painful nor pleasant and has purity of mindfulness due to equanimity. These, friend, are the four conditions for the attainment of the release of mind that is neither painful nor pleasant."
"But, friend, how many conditions are there for the attainment of the signless (animittā) release of mind?"
"Friend, there are two conditions for the attainment of the signless release of mind: non-attention to all signs (nimitta), and attention to the signless element (dhātu). These, friend, are the two conditions for the attainment of the signless release of mind."
"But, friend, how many conditions are there for the persistence of the signless release of mind?"
"Friend, there are three conditions for the persistence of the signless release of mind: non-attention to all signs, attention to the signless element, and a prior determination (abhisaṅkhāra). These, friend, are the three conditions for the persistence of the signless release of mind."
"But, friend, how many conditions are there for emergence from the signless release of mind?"
"Friend, there are two conditions for emergence from the signless release of mind: attention to all signs, and non-attention to the signless element. These, friend, are the two conditions for emergence from the signless release of mind."
