The two essays published here were written on the basis of lectures given to members of the School for Spiritual Science. Their content therefore deals directly with the path of inner development outlined in the lessons of the First Class of the School.

In the first essay, Selg address the necessary confrontation with the powers of evil as they appear in the Class Lessons and in our time more broadly. Only through confronting and overcoming these powers are we able to find the path to our true humanity.

The second essay deals with the figure of the Guardian of the Threshold as a Michaelic teacher and guide along the soul's path into the spiritual world. This figure, Selg argues, is far too little understood in our time. He is a spiritual being of great significance who offers help to all earnest seekers.

This book represents an ongoing effort on the part of Peter Selg and the leaders of the General Anthroposophical Section at the Goetheanum to deepen and internalize the work with the Class Lessons for all members of the School for Spiritual Science.
