Consider this fact about solar eclipses: A solar eclipse can only occur during the day, on a new moon. This means that you are working with new moon energy, which is great for getting rid of things and letting go. A solar eclipse does not have to be visible for you to work magic.
Working magic during an eclipse is rather advanced. In order to understand the energy of an eclipse, you must understand the energy of time and of the seasons. You must also be able to raise and focus energy within a quite limited amount of time.
During an eclipse, some people may sense a time of stillness, others experience a feeling of uncertainty. You may experience either of these like the tiny glimmer of time before a pendulum swings back after having swung all the way in one direction. This is the essence of an eclipse, and is a similar sensation to that felt within a magic circle.
Consider this fact about lunar eclipses: A lunar eclipse can only occur during the night of a full moon. This means you will be working with full moon energy. A lunar eclipse does not have to be visible for you to work magic.
Magic spells performed during lunar eclipses combine the power of the full and new moons simultaneously. Therefore, consider carefully your wishes. Any spell performed during a Lunar Eclipse must be done carefully, as one is invoking the Triple Goddess in each of her forms. Consider carefully what you wish and write it out beforehand.
