I agree with this post. I have read some books where the author suggests some pretty outlandish things to the readers. Someone could get hurt or worse doing some of the crazy things some gurus put out there. I think this is a good call on the part of SF.

And might I add; sun gazing????? What einstein cooked that idea up? Such a practice better give the practitioner some serious third eye sight.. because their physical eyes won't be working for too long if they engage in something like this.
