do you 'cast' coins when your on the go?

"Doesn't having a computer do it kind of take something out of it for you?"

Oh, no. Not for me. I think of computers as the ultimate in flat surfaces. I think it works much better, to tell the truth. If it works, it works, IMO. It's the dialogue with the Ching that's important, not the mechanics so much.
Computers are Tao as they can be, nothing but little Yang 1's and Yin 0's combining to make reality. The Ching, in the language i use with it, uses the hexagram #50, the cauldron, to indicate computers. The same hexagram that refers to the Ching itslelf. A transformative vessel that is a good product of civilization.

But people are different in this regard, and everyone has their own relationship and language with The Book.What i am thinking when i make a throw is of utmost importance to me. How i get the reading, not so important.

If i'm away from home and don't have a laptop, i use pennies. I know the hexagrams and lines well enough from long time heavy use that i usually don't reach for a translation, but instead remember what the line has meant to me before, and usualy remember various translations of the line. I have a strong personal dislike for ceremony anyway.
