The following lectures were given in Pretoria, South Africa, between 5th February and 24th June 1952. (The same also being given earlier in Johannesburg between 4th October 1951 and 3rd April 1952). The Lecture Notes could be purchased in blocks of ten prior to the series being given. A full account of these lectures combining the Lecture Notes and a transcription into text of the 19 known sound recordings have never been made public until now. This edition is now the definitive version of the full inner course as given by Murdo to his South Africa students. In this series of Lectures, Murdo goes much deeper than before, the most thought provoking to date, revealing more of the Inner Teachings of the Ancient Ones as given to him by the Masters in Tibet.
