The ancient divination method of the I Ching or “Book of Changes,” was reportedly the casting of tortoise shells. Later, the stalks of yarrow flowers were used, and are still considered the highest form of reading the I Ching.

The problem with tossing the yarrow stalks is that it’s extremely complicated. You’ll need 50 dried yarrow stalks (these may be purchased online or in stores that specialize in spiritual tools and books) and use them to cast your hexagram.

First, remove one stalk from the pile and set it aside. Randomly divide the remaining stalks into to piles. Take one stalk from pile on the right and hold it between the ring finger and little finger of your left hand.
