In this article, we report some excerpts from the writings of Dr. A.M., an adult female, regarding the knowledge she acquired during the regular mystical experiences she has been having since April 2014. This case is exceptional for multiple reasons. First, she experienced this particular state of consciousness without any associated medical or neurological illnesses. Second, these experiences did not harm her professional or personal life; rather, they have had, and continue to have, a positive impact on her life. Third, her case is exceptional because of the stability and longevity of her involvement with mystical experiences. And fourth, the knowledge she has been acquiring encompasses philosophically, religiously, and historically relevant aspects, the content of which extends far beyond her personal cultural and scientific knowledge. This case of a modern mystic supplements our traditional cultural and scientific ideas about the relationship between ordinary human mind activity and spirituality and between our inner and outer worlds.
