The Goetheanum glass windows are designed by Rudolf Steiner and the russian artist, Assja Turgenieff, brought the design for the second Goetheanum to form and artistic expression. The glass windows represent the stages of a path of inner development. Various motifs are touched upon: as the search for self-knowledge, the struggle to attain a soul equilibrium between the hardening and dispersing forces, the Source of and the right interaction between Thinking and Willing, the experience of the boundaries of death and birth and perspectives on human and world-development.In viewing and contemplating the colours and forms of the windows, an experiential perspective into the spiritual dimension of our existence is revealed.
