it seems to me that it is better for a person to develop their own relationship with the oracle via the coins and text.
i've had mixed results trying to help other people with the i ching,
whereas my personal results have been very accurate.
but i think it could be possible to do readings for others if you are intuitive and have a deep understanding of the i ching.
i'm only just getting to know the hexagrams and there connections!

Hi, with a few friends, I've offered a technique to them. I tell them to write down their question, but don't tell it to me. I then tell them to throw the coins 6 times, and write the results. With each throw, I tell them to meditate on different aspects of their question. With their results, i generate the hexagrams. I use both, "The I Ching Workbook" by Wing, and "The I Ching" by Wilhelm.

Say they have 22, 3rd & 6th changing lines --> 24. Then I would read to them, or photocopy, Wing 22, Wilhelm Book 1-the text 22, then Wilhelm Book 3-the commentaries 22. Then I would have them read Wing 22 line3, Wilhelm 22 line 3, Wilhelm 22 line 3. Then back to Wing for 22 line 6, and so forth.
This is how I do it for myself, also. Then, if they have questions, I try to help with interpretations. Usually they end up telling me their question, and then I can be more helpful.

This way is tedious, but it has a couple of advantages. They are trowing the coins, and they get the material to interpret themselves. I've been given their coin toss info. over the phone, and the next day, I bring them the results. This works a lot easier if you have a photocopier handy. Then you draw a lot of circles, and arrows, writing, "read this 1st, read this 2nd, etc.

It's a clumsy process, but more then one friend has become a believer. Good Journeys, Wayfarer1
