Book excerpt: Kharis: Hellenic Polytheism Explored delves into the many aspects of the revival of Greek paganism, from its ancient roots to its contemporary practice. It is written as an introduction for those new to Hellenismos, and as a reference for more experienced devotees. It covers not only the basics of worship, but also how to adapt the ancient religion to our modern lives, cultivate relationships with the gods and spirits, and create a deeply satisfying spiritual life. The emphasis of this book is on the concept of kharis - the reciprocity so implicit in the practice of Hellenic polytheism both in antiquity and today. From the simplest prayer or libation, to direct encounters with deities, the principle of reciprocal favor governs the heart of this religion and facilitates for each worshipper a real and profound connection with the divine.
