How Does Mind Consciousness Hand Over Problems to the Manas for Deliberation?

Let the mind consciousness package and condense a question, then hand it over to the manas. This method works as follows: the mind consciousness transforms the entire meaning within the question into a single thought, suspending it in the manas—that is, in the depths of the mind. No matter what one is doing, one must carry this questioning thought in the mind, carrying it deeply, without abandoning or letting go of it. If that thought is no longer in the mind—if there is no more doubt, no more deliberation—the mind consciousness should throw that question to the manas again, reminding Him once more. At the same time, the mind consciousness itself should not engage in excessive or complicated mental activities, so as not to distract the manas's attention. This is exactly how Chan Buddhism investigates a huatou in Chan meditation—the method is the same, and this is how the deepest and most subtle deliberation is done. Many people in worldly affairs have used this method; they simply have not been able to summarize and generalize it for use in the Buddha's teachings.
