Some questions regarding Secrets of Wilder

I’m new to AYP. I just recently bought pretty much everything I could get my hands on, and have been devouring The Secrets of Wilder. The book is very good so far, but I was wondering about the secret chamber part. Has anyone actually done this? I would assume that it would not have been included in the book if we could not all do it, but that is something I have never heard of before and it was pretty out there.
Just looking for any input, thanks.

A lot of us here do it. Here is a video of it!

Check out the online lesson on Kechari, too.

Hi ckdCosmo, and welcome!
Very happy to hear you are enjoying the Secrets of Wilder – a story near and dear to my heart.
The practice is called “kechari mudra.” It is covered in the AYP Easy Lessons book, and the Asanas, Mudras and Bandhas book.
You can also read about it online, beginning here: http://www.aypsite.org/108.html
It is discussed a lot here in the forums too.
All the best on your path. Enjoy!
The guru is in you.
