Yes, but what were the training courses on? Telepathy and time travel, among other things. If the author really "mastered the training courses" for these items, she could have gone back in time and used telepathy to prevent J.K. Rowling from writing the evil Harry Potter books!
OK. Funny. Ha. Ha.
Seems to me the author's point was that she was a part of this whole new age/occultist industry.
She describes herself as "a former New Age "healer" and advanced yoga practitioner" who was "in the business of the new science of the mind."
Her ironic tone indicates she didn't actually believe in the "arts" --telepathy, necromancy, geomancy, time travel, etc.-- she was "teaching."
So I see no justification for your or ctdonath2's distortion of her meaning.
