@SabahSnoblod Hello. I’ve used the I Ching extensively for years; it’s my primary method of divination. With that said, I’d recommend you get at least 2 - 3 reliable translations. Of course the “tried and true” would be the Wilhelm / Baynes translation, but aside from that it’s a good idea to have at least one or two other translations for reference. The language and metaphors is archaic and much is lost in translation into english, so it’s important to have a decent translated version. I’d strongly recommend you stay away from most modern versions in which the author took it upon himself in creating his own personal rendition.
Alexander12 gave a good rundown on most of the known methods of working with it. The yarrow stalk method is ancient and in my opinion not necessary; you can if you like the aesthetics of it, but it’s not required. I’ve used the method with the 3 coins for the first two years or so; it works, although sometimes the coins can roll under furniture and such. I’ve since moved on to a much simpler and convenient method, and it’s served me well: I use 16 cards with either a yin/yang line drawn on the back to draw from, much like in cartomancy. Traditionalists will no doubt stick their nose up and blah blah about accuracy and such, but frankly it’s all bullshit because my experience over the years using this method says otherwise.
