Orphism and the Initiatory Tradition
Historians and ethnologists argue and attempt to establish  whether this "myth" or that Deity, concern one or another people.  In the  same way, many historians of philosophy seek to demonstrate that the  philosophy of Pythagoras, Parmenides, Plato, Plotinus, etc., is purely  personal and original;  the development of the author's intuitional mind.   They believe that the consideration of Dionysus, Isis, the Indian Mahadeva,  or Pythagoras, Plato, etc., in an impersonal or supra-national way, is to  make too little of the intuition of the founders of "myths".  Often,  orthodox historians try to individualize knowledge by setting up altars to  the individual creator of "systems", be they religious, philosophical or  scientific.But, if one has the capability to approach what these minds actually  said, surmounting individualistic and often merely parochial attitudes, one  will be able to tell, without any fear of being mistaken, that the essence,  the theme, and the noumenon in every traditional philosophy, religion or  science are identical.  Obviously, each being, depending on its degree of  consciousness and intuitive-contemplative awakening, adorns that essence  with wealth and beauty of form, but above all with the power of his own  consciousness vibration or irradiation.
