Nothing is random. We know this now. What we call random is more the mark of a system that we cannot statistically account for and thereby appears to us random given the lack of understanding of how it gets from a certain action to a certain outcome. Cryptographers try to find ways around it, science battles with it, and mystics and diviners use it.
In my reading of it, the double slit experiment tends to suggest our actions are imbued with the intention behind them. I'm seeing support for the idea that matter arises from consciousness, not the other way around. An electron shot straight through one of two slits in a metal sheet took the path through the slit it was pointed at — when observed. When not observed, it behaved impossibly — an interference pattern built up one electron at a time, which is only possible if electrons went through both slits.
It's called the observer effect. Though I don't doubt that the act of observing it is what affects the outcome, I think there's more to it. Observing something comes with the expectation of what that thing will do. For expectations so engrained as to form what we all agree is reality, that expectation is accompanied by the intention that it will happen. There are many esoteric schools that equate perception (expectation / observation) with will (intention), but that's not a matter for the present discussion.
If I'm reading the words between the lines properly here, this suggests our expectation of what happens and the extent to which that seeps into our intention (depending upon the unquestionableness of that expectation), affects the behaviour of outcomes in the physical world. Intention interacting with outcome in a situation where the outcome seems unquestionable.
The quantum wave function, waves of probability existing around us, each holding the potential of every decision we can make in a given moment and every outcome for each decision, is the probability amplitude at play here. Actions in the context of certainty create expected outcomes. Actions in the context of systems sufficiently complex are not subject to the same certainty of expected outcomes. In such actions, our consciousness does not interfere with the actual outcome by way of an expectation as to what will happen because it defers to the apparent randomness of the action. This makes way for our intention to make an impression.
Well, what about where the action is throwing three coins (a seemingly random action), and the intention is a question — what then? Couple that with the context in which the coin tosses are applied to a comprehensive and well rounded system of archetypal symbols that describe every species of happenstance we encounter in our lives — and you get an answer to your question, offered up by the interplay of intention, our stochastic, probabilistic universe, and a cipher system sufficiently complex and comprehensive enough to decode it.
Put another way because that's a pretty nuts idea as I reread — Three coins. A comprehensive, well-rounded symbolic cipher that apportions archetypes to a combination of tosses. A throw of the coins imbued with the intention of our question. Zero conscious interference given acceptance that the action is random. When coupled with the idea of the interplay of intention and outcome — perhaps it's a mechanism by which a response to a question may be induced from the ever present universal consciousness.
In such a way, the I Ching appears as a manual kickstart to an all pervading quantum computer that answers our queries by the intersection of a system sufficiently well rounded enough, and an action (tossing coins) unpredictable enough that our conscious expectation can't interfere, and insights can be derived by the symbolism that is thereby manifested. The book we translate the I Ching from is three thousand years old, but even then it was ancient.
I'm not claiming to have cracked the science behind divination or anything — just highlighting how it is that systems such as the I Ching, or even tarot, coffee cup or tea leaf reading, are emerging as perhaps an incidental, residual, anomalous effect of our stochastic, probabilistic universe.
Use the I Ching regularly. Sit with the results in the knowledge that you have an actual response from forces beyond your comprehension. myJING brings the I Ching, Six Lines, and BaZi together, to offer up a comprehensive lattice / scaffold to the universe that any one system can't provide on its own, and on which it may impress the answer to your question with the precision and illumination that speaks clearly to your intuition, and from which you can derive penetrating insight.
