In this book, Ervast offers unique perspectives on spiritual evolution, which is called the way of initiation in the theosophical circles. He begins by discussing the required conditions for a true spiritual path. Ervast emphasises that one cannot advance on any occult way unless one has first gone through the initiation of compassion.
The aim of esoteric teaching has always remained the same, but the methods have changed as human consciousness has evolved. Ervast talks about the initiation ceremonies in ancient Egypt as an example of the Old Covenant method. He goes on to describe how Jesus Christ opened a new way of initiation, the New Covenant, and how this changed our relationship with our higher self, the Mystical Christ, and the invisible world.
