This study is obliged to the "Marburg School of the Science of Religions" (R. Otto, H. Frick, K. Goldammer, E. Benz). The methodological concept follows the comparison of religions, as it is classically demonstrated by R. Otto in his work about "West-östliche Mystik" concern-ing the contrasting of Shankara and Meister Eckhart. That the comparison of the figures of the masters which is practised in this school may yield good results is also proved by G. Mensching, Otto's disciple in Bonn, in his book on "Buddha und Christus - ein Vergleich" and H. Frick, Otto's successor on the Marburg chair in Systematic Theology, in his early trea-tise upon "Ghazalis Selbstbiographie. Ein Vergleich mit Augustins Konfessionen". Spe-cial emphasis should be given to the attempt of F. Heiler who as early as in 1918 contrasts Buddha as a "master of contemplation" to Jesus as a "master of prayer" in his work "Die bud-dhistische Versenkung". All the mentioned attempts are based on the eminent enquiries in the field of the common history of religions and the psychology of religion as R. Otto's "Das Heilige"  and F. Heiler's "Das Gebet". Worth mentioning is also the comprehensive study of the Marburg church historian and distinguished authority of the Asian religious world, E. Benz, about "Die Vision". Benz, also a disciple of R. Otto, was a famous re-searcher of mysticism and spiritualism as well (Joachim of Floris, J. Böhme, E. Swedenborg). ..
