Wicca is nature-oriented. It is a type of religion that worships both the male and female aspects of god. But more importantly, Wicca places a high value on common-sense dealings with the environment.
Wicca needs no formal atmosphere nor other people to be effective. Wiccans achieve an honest and clear relationship with all elements through quiet communication, often in solitary.
To a Wiccan, magic is simply influencing their environment with what can be boiled down to nothing more than unconditional love for oneself and all other things both material and spiritual.
