Do the Six Consciousnesses Have the Dharma of Sleep?

Whatever dharmas the six consciousnesses may have, they must exist under the condition that the six consciousnesses exist; if the six consciousnesses themselves do not exist, how can one even speak of possessing any dharma? For example, if there is no person named Zhang San, one cannot say that Zhang San has any possessions; if there is no house, one should not talk about what is inside the house. By the same reasoning, during sleep there are no six consciousnesses, so one should not speak of the six consciousnesses possessing the dharma of sleep. Then whose dharma is sleep? It is the dharma of the manas. Although the manas does not sleep, the manas requires sleep according to the condition of the body, in order to resolve the problem of bodily fatigue and weariness. If there is no sleep and the body is exhausted, the manas cannot normally use the six consciousnesses to complete various tasks. That is to say, sleep is what the manas needs, is decided by the manas, and is an active behavioral choice of the manas. The purpose of the manas choosing sleep is to enable the five-aggregate body to work better. If the five-aggregate body is not fatigued and weary, the manas will let the five-aggregate body continue operating without interruption—this is exactly how the heavenly beings are. Therefore, sleep corresponds to the manas, not to the six consciousnesses; only when the six consciousnesses cease does sleep occur.
