Candles-Straight or votive candles in the following colors:
one purple (spirit contact, divination), one white (purity, balance
the aura, raise the vibrations), one silver (develop psychic
abilities, raise the vibrations), and one light blue (wisdom,
harmony, contacting the Higher Self).
Oil-Honeysuckle or myrrh.
Herbs-Orris root.
Incense-Wisteria or lavendar.
Stones-Amethyst, flourite, moonstone, and clear quartz
crystal.
Other Supplies-Whatever divination tools, such as tarot
cards or runes, you plan to use.
Timing-On the full moon or waxing moon cycle.
Day-Wednesday or Monday.
Advice-Skill in any form of divination takes practice.
This spell will help you open more easily to spiritual aid.
Spellwork-Light the altar candles and the incense. Arrange
all the divination tools in the center of your altar space. Anoint
all of the candles from the wick to the end. Place the white
candle at the upper left of the altar with the moonstone to
the left. Put the silver candle at the upper right of the
altar with the clear quartz crystal to its right. The purple
candle goes below the white candle with the amethyst to its
left, while the light blue candle goes below the silver candle
with the flourite to its right. By situating the candles in
this manner, you can safely practice your divination in the
center without disturbing the candles. Say the chant. Then do
whatever divination method you planned. Leave the candles to
burn out completely. Dispose of the wax afterward.
Chant-
Unlock the secret inner door. Give to me the key,
That reveals the aged secrets. Let me the future see.
Grant wisdom for enlightenment, understanding, more.
Sweet Spirit, lead me inward to the hidden sacred door.
