Calendar of the Soul

Northern Hemisphere
Week 13

And when I live in senses' heights,
There flames up deep within my soul
Out of the spirit's fiery worlds
The gods' own word of truth:
In spirit sources seek expectantly
To find your spirit kinship.

Southern Hemisphere
Week 39

Surrendering to spirit revelation
I gain the light of cosmic being;
The power of thinking, growing clearer,
Gains strength to give myself to me,
And quickening there frees itself
From thinker's energy my sense of self.

—Translation by Ruth and Hans Pusch

Second Scientific Lecture-Course:
Warmth Course
GA 321

Rudolf Steiner discusses the nature of warmth, its relationship to the four states of matter, to light, to color, and to the sub-earthly and super-earthly realms. He strives to extend modern ideas of physics through the understandings achieved by spiritual science. With extensive notes and diagrams, this work comprises essential reference material for teachers of the natural sciences, as well as interested parents and others.

The Second Scientific Lecture-Course: The Warmth Course (The Theory of Heat) — This publication is intended for those with a serious interest in the extension of modern scientific ideas about the physical sciences.

The title, in German, is: Geisteswissenschaftliche Impulse zur Entwickelung der Physik. Zweiter naturwissenschaftlicher Kurs. Die Warme auf der Grenze positiver und negativer Materialitaet.

This lecture series is presented here with the kind permission of the Rudolf Steiner Nachlassverwaltung, Dornach, Switzerland. Translated by George Adams with editing by Alice Wulsin and Gerld Karnow.
