well most would argue about the lunar cycle, i saw whenever you feel a your most strongest and when it is necessary, im certainly not going to wait until a full moon, for a money spell, when i need in as soon as possible.
i think if you meditated and have complete focus on the spell you are about to perform as well as using aids such as crystals and candles then it doesnt matter what time of the month or day you perform it. the power comes from within you, i think the lunar cycle only aids the spell. i could be wrong but that is what i believe in. that is how my power appears to work.
