Calendar of the Soul

Northern Hemisphere
Week 35

Can I know life's reality
So that it's found again
Within my soul's creative urge?
I feel that I am granted power
To make my self, as humble part,
At home within the cosmic self.

Southern Hemisphere
Week 9

When I forget the narrow will of self,
The cosmic warmth that heralds summer's glory
Fills all my soul and spirit;
To lose myself in light
Is the command of spirit vision
And intuition tells me strongly:
O lose yourself to find yourself.

—Translation by Ruth and Hans Pusch

The Light Course
GA 320

Rudolf Steiner's course on Light, which includes explorations of color, sound, mass, electricity and magnetism, presages the dawn of a new world view in the natural sciences that stands our notion of the physical world on its head.

This ‘first course’ in natural science, given to the teachers of the new Stuttgart Waldorf School as an inspiration for developing the physics curriculum, is based on Goethe's approach to the study of nature. Steiner corrects the mechanistic reductionism practised by scientific positivists, emphasizing instead the validity of human experience and pointing toward a revolution in scientific paradigms that would reclaim ground for the subject — the human being — in the study of nature.

Published in German as, Geisteswissenschaftliche Impuls Zur Entwickelung der Physik. Erster naturwissenschaftlicher Kurs. Farbe, Ton, Masse, Elektriitaet, Magnetismus. Authorized English Translation by George Adams M.A. from the 1925 Edition of the Original issued by the Natural Scientific Section of the Goetheanum, Dornach, Switzerland
