How to Enable the Manas to Contemplate Problems Without Affecting Sleep?

If you want to assign some tasks to the manas before sleep, so that the manas can ponder a question during sleep without affecting your sleep, then the manas needs to be very familiar with this question, to know what the content of the question is, without needing the mind consciousness to help analyze it further, and without needing the mind consciousness to transmit any further information; moreover, the question should not be urgent to resolve, and there is no need to know the answer right away. In this way, the manas will be at ease letting the six consciousnesses cease.

After assigning the task and posing the question to ponder, do not do anything else, and do not think about anything else either—just go straight to sleep, letting the manas hold only this one matter in mind, unaffected and unobscured by other things. When the manas needs to activate the mind consciousness to assist its deliberation, it is certainly because the question is not yet very familiar and it cannot find the approach or direction for a solution, so it needs the mind consciousness to help analyze and provide information for reference. If the manas is very familiar with the question and has a method of solution, then even if the mind consciousness wants to help analyze it, the manas will not use it, considering Him an obstruction.
