If you get a rudimentry working knowledge of the I Ching or Book of Changes, you'll find it a very useful tool. Preferably the Wilhelm/ Baynes translation, all though others may be equally telling. The hexagrams are read from below (interior) the lower trigram, upward (exterior) the trigram above. Readings of the interior trigrams are also nicely translated in:
Wilhelm/ Baynes, 1950
Princeton University Press.
The title of this piece is linked to an informative site on this translation and the tradition on which it's based.
Today thinking of the poem listed under Monkey Trials below, I read from the I Ching # 24. Fu / Return, (The Turning Point)
(I wish I could share an artful rendering of the pictogram here).
Below: Chen The Arousing, Thunder
Above: K'un The Receptive, Earth
Read it as though looking through a holograpic image
