Martinus gave lectures about his world picture throughout his life, both at the Martinus Institute in Copenhagen and at the Martinus Centre in Klint, near Nykøbing Sjælland. Many of these lectures were taped and thereby preserved for posterity. He regarded his lectures as a showcase for his cosmology because he could not always substantiate his analyses in that rather brief form. He referred therefore to his main works for a more thorough study of life’s major analyses. Many people felt uplifted by Martinus’ lectures and left with renewed zest for life and inspiration to solve everyday problems.
