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.
Let's look at her exact words:
Before my audience is lost too, considering me a fear-mongering, fundamentalist, unimaginative critic of the series, may I introduce myself as a former New Age "healer" and advanced yoga practitioner. Many of the delightfully described magical arts in the Harry Potter series were pretty standard fare in training courses I mastered to some degree or another, including telepathy, divination, energy-work, necromancy, geomancy and time travel, to name but a few. I was quite close friends with wizards, warlocks and witches alike - all of us (psychologists, physicists, & other professionals) being in the business of the new science of the mind, defending our studies together as being of the white magic category, much like the wizardry school of Harry Potter.
Where's the ironic tone? I don't see it. She claims she "mastered" training courses in "telepathy, divination, energy-work, necromancy, geomancy and time travel." If she were stupid enough to believe in that garbage in the first taste, why should we listen to what she says now?
