I have been a devotee of Kirpal Singh for over thirty years now, 
and have simultaneously practiced general medicine and psychoanalysis for almost the same period of time. Based thereupon, I feel a distinct urge of taking on the challenge of scientifically estimating and critique the life and teachings of Kirpal Singh and yoga generally, though I may fall short of the mark because of the significance of his personality.
Nevertheless, a beginning must be made. The discrepancies between West and East have occupied me for too long. Even though Kirpal Singh often stressed, that R. Kipling's statement "East is East and West is West and never the twain shall meet" were unjustified, he by far wasn't able to dissolve the cultural and especially the scientific-spiritual differences, between East and West. His 'successors' are still selling exclusive Indian-esoteric wisdom, and as a psychoanalyst, I am impelled to contradict. This is supported by the fact that some conclusions made in the lifework of French psychoanalyst J. Lacan, exactly coincide with the teachings of Kirpal Singh (Surat Shabd Yoga). Lacan ties psychoanalysis to linguistics and to modern geometry. He ties them to the yoke ('Yoga') of sciences with the help of a yoga-like topology.1 Lacan's linguistic on the other hand deals very well with the structure of yogic mantras. The application of such puts us in the position of not only explaining Kirpal Singh's yoga, but Yoga in general, whereby our support would be accurate modern sciences. We need not rely on widespread contemporary pseudo-science, but instead pay tribute to Kirpal Singh's 'mission'. Consequently, I will often refer to Lacan's findings in this book. This, though, will lead to the construction of an independent therapy, as you can't simply mix Yoga and psychoanalysis.
1 Topology is a modern geometry and is also called 'rubber geometry, because lines in space may also appear to be bent according to Einstein's theory, i.e. the angular sum of a triangle can be greater (e. g. drawn on a sphere) or smaller than 180°.
