State the purpose for the moon bath. Speak to the crystal and to the moon. While you are placing your crystal under the moon, be sure to take a moment to gaze at it under the beautiful soft light of the moon. In time, you may glimpse a moon-rainbow or two. Each time you do this, it will reach a greater level of aliveness.
Crystals love to be used.
Use them powerfully, cleanse out what they have taken from your work, and then re-empower them. It is the cycle of a working crystal. Again, there are several ways to power up a crystal. Be sure to follow your intuition. However, no matter the method you use, you will be using your intention to enliven your crystal.
