To adorn your walls with the Green Man and the Goddess.
The Green Man is used as a symbol of seasonal renewal and ecological awareness. In Wicca, the Green Man has often been used as a representation of the Horned God, a syncretic deity that appropriates aspects of, among others, the Celtic Cernunnos and the Greek Pan.
The Goddess is seen as the Triple Goddess, meaning that she is the maiden, the mother and the crone.
