Modern Pagan: How to Live a Natural Lifestyle in the 21st Century, by Brian Day. A guide to harmonious, natural living through modern pagan principles. Paganism is a sustainable way of life that has existed for thousands of years. Sometimes mistaken as a religious path (true pagans do not worship deities), paganism will appeal to anyone who cares about the environment or is interested in maintaining an organic lifestyle. Although it is an ancient practice, paganism is particularly suited to meeting 21st-century concerns. In The Modern Pagan, Brian Day explains how to live in a way that honors the land and its inhabitants, offering advice on cultivating a true pagan garden, creating nutritious food and drink, celebrating seasonal festivals, practicing herbal medicine, and working for the benefit of all.
