Personally, I've come to prefer the I Ching to Tarot for in-depth questions, it's easy to understand (or rather, I find Tarot much more difficult to interpret).
Paradoxically, I prefer the Wilhelm-Baynes translation to all of the modern translations I have tried - it requires an amount of background knowledge about Confucianism and Daoism to grok what it's getting at, but something always seems to be lost in "plain modern english" type paraphrasings. If anyone knows a good one I'm all ears.
To cast my hexagrams, I use a four-coin method of my own devising which is based upon an alternate three-coin method detailed in The I Ching Handbook by Edward Hacker (my indispensable resource). This alternate method produces identical odds for each type of line as the traditional Yarrow-stalk method. It works like this:
- Get four coins. At least one should be distinct from all the others. I use three US eagleback quarters and a Sacajawea dollar from 2000 (which also has an eagle on the back).
- For our purposes here, I will call the distinct coin the "big coin" and the others the "small coins"
- Throw all of the coins together.
- Check the big coin. If it is heads, your line will be Yang. If it is tails, your line will be Yin.
- Check the small coins.
-- If the big coin is heads, and ONLY two of three small coins are also heads, the line is moving yang, value 9. Otherwise the line is static yang, value 7.
-- If the big coin is tails, and ALL of the small coins are tails, the line is moving yin, value 6. Otherwise the line is static yin, value 8.
For more on-the-fly type stuff, or when I need SPECIFICS RIGHT DAMN NOW, I've come to adore my pendulum. Over the years I have asked it many questions which later had definite answers, and to the best of my knowledge it has not been wrong one single time. It's a pocket sized oracle that produces instant yes/no answers, can be used to locate objects via dowsing, and in tandem with a semicircle of letters can serve identically to the ever-popular Ouija board. It's dead simple, infinitely applicable, and cheap to assemble or purchase, perfect for the absolute beginner.
Overall I've found the thing that helps most regardless of the tool or technique is *asking the right question* - what you get out will generally be as specific as what you put in. And the thing that helps the second most is don't worry about doing it "the right way", trust your intuition to guide you, and your oracles to speak true.
