  Vortices and the Psychic Tide Everything that exists has energy which is held together by vibration and frequency. Anything that has energy can affect our energy, like crystals, essential oils, perfumes, incense, places and color, as a few examples. Some places have powerful energies called Vortices. These are powerful energy centers and are also called Chakras of the Earth. They are sacred sites. In some of these areas healings have taken place and people go there for pilgrimages. Artificial Vortices can be created consciously and unconsciously by living everyday. You can create a Vortice intentionally too in a temple or a place where magic is performed. It can be imbued with psychic energy which can turn it into a powerful psychic Vortex, which will strengthen the abilities and perceptions of all who enter.
The Psychic Tide is a continual cycle of time. These cycles range from the time it takes our Planet to revolve upon its’ axis (24 HRS) to the length of the so-called Great Year (19,200 years, according to the Correllian system). This energy is like the tide of the ocean. When the tide is in its dark half, the energy is moving inward.
When the tide is in its light half, the energy is moving outward. They both need each other for balance. They can't survive without each other. The moons are also explained by the light/dark analogy, this is the monthly cycle. There is also the yearly cycle which is the winter/spring. The winter is the dark half and the spring is the light half. The Wheel of the Year The Wheel of the Year comprise the 8 Sabbats and 13 Esbats. The Eight Sabbats are divided into two sets of four. These are the Grand Sabbats, which are feminine and dedicated to the Goddess, and the Lesser Sabbats which are masculine and celebrate the God. The Lesser Sabbats are in nature, Solar as are the Equinoxes and Solstices of the Sun, on which the Solar calendar is based.
As the year is divided into a Dark and a Light half, there are two Grand Sabbats and two Lesser Sabbats in each. The Sabbats are: Samhain, Yule, Imbolc, Ostara, Beltane, Litha or midsummer, Lammas and Mabon. Esbats are the moon festivals. They honor Deity, and are more personal. This is when more spell workings are done. Esbats are held usually on Saturdays closest to the New or Full moon. New moon Esbats are held at the very beginning of the lunar cycle, the Light half of the month. Full Moon Esbats are held at the end of the Light half of the month. The moon is at its strongest point then. Doing magick at this time will give more energy to the work.
