This is a method of Shamanic Divination. It has a total of seven stone or beads. The color of the stone or beads should be white, red, orange, yellow, green, blue, and violet (purple).
The Yes/No Technique:
Use only the white, red, and green stone. The white stone means kumu the "foundation" while the others are called eo meaning "answering". This means whatever stone falls closer to the white is the answer. In this technique the green stone means yes while the red one means no. This technique is only for yes and no questions. So don't use it on any other types of question like should and why. Ask your stones in your hand like any other question you would (remember to be clear) and toss them when your ready.
