9.57

This evaluates it as being false. Failing to understand that the essence of false thoughts is empty, they cling to arising and ceasing as tiresome, reviling this arising and ceasing to seek non-arising and non-ceasing; hence it is said, 'takes arising and ceasing as the cause.' Casting off arising to head toward non-arising is not yet true non-arising. Seeing that the sixth consciousness temporarily does not function, like a fish encased in ice, and unaware of subtle arising and ceasing, they falsely call it nirvāṇa, but it is not true nirvāṇa; hence it is said, 'they cannot illuminate the nature of non-arising and non-ceasing.' 'During the first half-kalpa' onward conversely explains the aspects of their retribution. In accordance with the *Kośa* citing the *Vibhāṣā* to explain the state of birth and death therein: for most of the time there is thought; when first born into this heaven, after half a kalpa, one first enters the vipāka of non-thought, which is called 'during the first half-kalpa it is extinguished.' When about to be impermanent [at death], one emerges from the vipāka, having a mind for half a kalpa, and only then dies, which is called 'during the second half-kalpa it arises.' Between arising and ceasing it is entirely without thought, so it is called the Heaven Without Thought.
