What Is A Sacred Circle?

Why is a circle used for everything done in wicca:

To protect you from outside energy, to hold and train and grow the energy before releasing it.
It is a safe place to come back to.
To protect yourself from everyone else’s energy in the circle.
To protect others in the circle from your energy.
To harness the circular energy of the universe.
To harness the energy of the elements and the spirit.
