All the types of crystals that I am going to discuss, except for the double terminates, are suitable for this type of mandala work. Your client, or healee, is placed inside the mandala, with the top point one hand's length above his head, and the lower point one hand's length beneath his feet. This will also activate the Alpha and Omega chakras of the healee. At one time we used to use copper wire to join up the crystals within the mandala, but we have now found that this is no longer necessary. Instead, you can use either another crystal, or a crystal wand, or even your fingers.
Intent is again all that is required.
Formulate the intent within your mind, as you move the crystal in your hand, or your wand, joining up each one of the crystals within the mandala. Start at the top of the mandala, the point above your client's head, and build the first triangle, all the time moving in straight lines from crystal to crystal. Then start at the opposite, lower point at the bottom of the mandala and join up the second triangle. By now you will feel a definite change in energy, confirming that the mandala has been correctly joined up and activated, as will your client, who is lying within the mandala.
