Fill the cauldron half-full of water and place it on a table where you can see comfortably into it while seated. Light two purple candles and place peppermint or mugwort in a simmering pot; for those who prefer incence, a mix of mugwort and wormwood work best. Arrange the candles so their light does not shine into the water or your eyes. Focus your attention on the bottom of the cauldron, your hands placed lightly on either side. Breathe gently onto the water. Say:

Cauldron, reveal to me
That which I seek.
Great Mother, open my inner eye
That I may truely see.

Empty your mind as much as possible; remain relaxed while looking deep into the cauldron waters. The answers may come in images in the water, pictures in your mind, and strong bursts of "knowing". The spell is best done during the Waxing or Full Moon.
