The Meaning of the Seven Eyes, Lamp stands in the Brain (Revelation).
"An eye is a symbol of perception. When signals arrive from the sensory layers (Smyrna and Ephesus), they make contact with the memory layer (Pergamum) in such a way as to form sequences. The sequences are organized into seven nodes each which is symbolized by the seven lamps. Joshua is an input pathway to a single node in a sequence. Each node (except the first one) receives a special input called the Branch. Likewise, each node (except the last) sends out a Branch output. This means that there are six branches altogether, which, if you'll remember, is the number of branches specified for the golden seven-lamp menorah in the Temple (see Exodus 25:31-40). The Branch is used as a corrective signal that compensates for Joshua's imperfection. This is symbolized in Zechariah's text by the iniquity of the land being taken away in one day.
Several questions arise. Why does a single node have seven eyes? How many ways are there to perceive incoming signals? In other words, what do the seven eyes really represent? In order to answer these questions, one must first understand what it is exactly that is being perceived. As was made clear in the message to the church of Sardis, memory has to do with the recording of intervals between certain events. The problem is that there is an infinite number of possible intervals between events, from fractions of a second to minutes, hours, days, weeks, months, years, etc...
In my opinion, the brain uses seven different precision windows to record intervals: the longer the interval, the lower the precision. This is the reason that we find it hard to remember what event preceded other events in the distant past. To compensate for this lack of precision, we find it necessary to use calendars and clocks. By contrast, we have little difficulty timing the motion of fast moving objects. For example, we can judge how fast a car is moving toward us so as to make a reasonable decision to move out of the way in time."
