Welcome to my book. A book about play in its most serious form – play as devotional practice, as worship. I worship the God of Play, and this book is a guidebook for worshipping this de- ity. It explains the God, details its powers, its qualities, its manifold forms, and describes the weighty resistances we face which prevent us from manifesting divine play. This book is a prayer book. It con- tains manuals of worship, pedagogies, and creative displays of this God’s powers. This book was able to be written only because I have had this God in my heart, or very near to my heart, or perhaps at ear’s distance able to be called upon by my heart and beckoned to come nearer.
