Biestmilch lives in a circular world. It is not a substitute for deficits, it is a substance that asks you to be ready to change your angle of reference, your observation point for coming closer to its value. In this world nothing is linear anymore, because it is all about regulation, about regulatory processes, and, regulation can never be linear from »A« to »B«.
If the input of signals only originates from yourself, in a situation like this where no outside world exists, human beings go crazy easily. Just think about dense fog, where you don’t see anything, no frame of reference, or in the desert, where the light can be so bright that you cannot discriminate either, no frame of reference, nothing that makes sense to you anymore.
