Devamitra, you seem to have researched those subjects, to what conclusion did you come: Can magic or other supernatural things alter the physical world?
By the very definition, these words refer to "unexplainable" phenomena men believe to have personally experienced or happened elsewhere; philosophically it hardly alters the subject if we accept the postulate that a rational explanation could be deducted for these deeds or events; it suffices that currently they are "unexplainable".
Consider for a moment finding yourself in possession of real
power, not a conjurer's trick. The capacity to harm enemies, to heal the sick, to control the climate (hello mr. Browning) would instantly, irrevocably, place you apart from mankind. Only by seclusion, even hiding, would you have a moment of peace. Could you ever be free from the notion that even your closest friends are merely trying to use you? Could you repel the doctors and the scientists and the businessmen, for whom you would be a rare prize object? And most importantly of all, how would you cope with events such as death, sickness, accidents and decay near or far, knowing that you could have reversed the process at any point?
Everything can be altered, and we are surrounded by a strange, cold, uncharted cosmos. But people looking for shortcuts, or answers to their problems, or a more meaningful life, hardly find them in the mazes of esoteric mind-science.
