Magic can be used to focus energy to effect change in the world, for the good of all. Cord magic is a great way to be clear in your intention and draw a desired effect into reality. Find a piece of string or cord about a yard long. As you tie nine knots in the string, say the following and let the power of your intention be focused and real:
By knot of one, this spell has begun.
Keep the knotted string on your altar, and renew the spell as needed.
