There is a reason this book does not print the exercises in full.

I chose not to set them out in depth or in detail, mainly from a fear of misinterpretation, and because of the difficulties, or the dangers, that someone without guidance might meet.

It would be inconsistent, I believe, to attempt a thing you have not fully interpreted and deeply understood.

Then comes the exception, which matters more than the rule.

The techniques are held back. The Prayer is refused to no one.
