|This is one way to use these beads to do a I-Ching reading.
It is suggested that we use the I-Ching as a tool to tap our subconscious knowledge rather than as a means to predict the future. Therefore ask yourself a question such as " What should I focus on in xyz situation?" or "What are my true feelings about such and so?", instead of " What will happen with xyz?"
Also, it is helpful to keep in mind a different aspect of the question when choosing each bead. You can call this "sealing a moment in time with intent". The idea being that there are always many different energies at play in any given moment and that your intent can be one of them - allowing your subconscious to pick the beads that will lead to the final hexagram. You choose each bead by running them through your fingers without looking and eventually stopping on one. The colour of that bead determines what type of line you draw.
Each of the colours of beads occurs with the same probabilities as can be found using the traditional yarrow stalks (oldest method). Each colour signifies a different type of line to be made to build a hexagram. (Black is yin, white is yang, red is changing yin, and ivory is changing yang). Hexagrams are created from the bottom up - so the first line (first bead chosen) is the lowest line. You create a hexagram by picking 6 beads and drawing each line above the last.
