Sometimes the solution is to sleep on it. Seriously, I once listened to a fascinating radio program about sleep, deprivation of, dream states, nightmares, the whole gamut. There is a sub conscious area of the brain that processes when the rest of you is "turned off" for the night. Often, when you awake, the solution, or at least a path to it, is passed to the conscious mind without you realizing it. Don't mean to profess a great deal of knowledge on the subject, but that's probably why we have the expression "sleep on it" and I for one, practice it when need be.
The more we hear silence, the more we begin to think about our value in this universe.
