Start the spell  before your exact birth time, hold your hands together and visualize how a white-golden energy ball slowly forming inside you. As soon as your birth-minute is, chant five times:

I have inner power, I am my inner power, by the power of my belief, the full moons energy and my birth time of turning ( your age), this is my will so mote it be!

While you chanting visualize how the energy is getting bigger and brighter, then visualize how the energy distributed throughout your body.
