The Effect of Occult Development Upon the Self and the Sheaths of Man
GA 145

Steiner delineates the almost imperceptible changes that take place in the physical body's experience of food as a consequence of spiritual development. He goes on to describe how we develop an inner experience of the etheric body and how our judgments, feeling, and willing are transformed. Gradually we are led to a direct perception of the reality of the great legends, notably the Paradise story and the Holy Grail legend.

These 10 lectures were given by Rudolf Steiner in March, 1913 at The Hague. They are a part of the lecture series entitled, What Significance Has Occult Development of the Human for the Sheaths: Physical Body, Etheric Body, Astral Body, and the Self, published in German as, Welche Bedeutung Hat die Okkulte Entwickelung des Menschen Fuer Seine Huellen - Physischen Leib, Aetherleib, Astralleib - Und Sein Selbst? (vol. 145 in the Bibliographic Survey).
