A waxing moon (the time from the new moon, through the first quarter, to the full moon) corresponds to the Maiden (also Warrior and Virgin) aspect of the Triple Goddess, and is the proper time for performing rituals in honor of Her.
It is also the appropriate lunar phase during which to perform spells and rituals involving all forms of growth, strengthening, and the increasing of things (such as love, good luck, health, money, and so forth.)
The energy of the full moon increases a Witch's psychic powers; therefore, the full moon phase is said to be the most favorable time of all to perform divinations as well as spells and rituals that increase psychic abilities and induce dreams that reveal the future or the unknown.
The full moon corresponds with the Mother aspect of the Triple Goddess, making it also a powerful phase for working all manners of fertility magic.
The moon has been associated with female fertility since antiquity, and at one time it was commonly believed that if a woman desired children, she could simply sleep under the silvery-white light of the moon and become magickally impregnated by a moonbeam.
Full moons also enhance the power of spells that involve creativity, nurturing, and sensuality.
A waning moon (the time from the full moon, through the last quarter, to the new moon) corresponds to the Crone aspect of the Triple Goddess, and is the proper lunar phase in which to perform spells and rituals that bring things to an end. This is the correct time to reverse spells (countermagick), and decrease, banish, and destroy things (such as diseases, addictions, a streak of bad luck, and so forth).
SPELLWORK BY LUNAR PHASE
The following is a list of different types of spellwork (arranged in alphabetical order), followed by the appropriate lunar phase/s during which each one should be performed. (If you are ever in doubt as to which phase of the moon is the correct one for a certain spell, I would recommend performing it on a night when the moon is full because this is the time when the power of magick is greatest.)
