Karl König meditated intensely on the 52 weekly verses of Rudolf Steiner's Calendar of the Soul. He often encouraged his colleagues to find inner strength from the verses, and wrote this book as a guide for them, drawing out the patterns through the course of the year.
There are also some lecture notes and additional essays.
This book will be a useful and inspiring guide for anyone who wants to fully understand and experience Steiner's Calendar.
There is also a separate complementary book, An Inner Journey Through the Year, which contains König's 52 color sketches based on the Calendar of the Soul.
