There are many types, styles, and structure. Often they are based on historical regional religions. With so many styles and forms, defining them is no easy task. However, there are some basic beliefs that most of us hold in common. Respect for Life, and the Earth, and the acknowledgment that Life is sacred.
Death is also an integral part of life, and sacred as well.
They cannot be separated, one does not exist without the other. Most of us believe in this in one form or another. That which you do, good or bad will be returned to you times three. Each person must find their own path. We do not attempt to coerce others to our path by outlawing other religions or by forcing our rules to become public law.
