The Chinese hexagrams are a binary code of a system just as encompassing as the tarot. Binary codes can encode anything a discrete code can encode, and are the basis of all modern communications. All images, all sounds, all thoughts can be hidden in strings of ones and zeros – broken/unbroken. Each new bit doubles the number of possible messages.
But sometimes one has to break out of the system.
Thinking outside the box. Breaking rules. Intellectual courage. New codes.
