As stated above, Paganism is not a revealed religion ‘of the book’ and there are no sacred scriptures as such. Perhaps the natural world could be said to be the sacred text. Some writings from the founders of contemporary Paganism have become well-known, with Doreen Valiente’s ‘Charge of the Goddess’ having become something of a sacred text for Wiccans. The following quotation gives a flavour of the language:

I, who am the beauty of the green Earth, and the white Moon amongst the stars, and the mystery of the waters, and the desire of the heart of man, call unto thy soul, arise and come to me.

For I am the soul of Nature who giveth life to the universe; from me all things proceed, and unto me all things must return.

Modern Heathens often draw on the prose and poetic Eddas (medieval Icelandic manuscripts), and reconstructionist eclectics might draw on other texts contemporary with their origins.
