When I first started doing AYP, I thought how it would be useful to have a video or something so look at to verify if I was doing the various practices properly. For example, Chin pump and so on.
Imagine if we could put together a AYP DVD that goes through a typical session. Where you can select an individual practice and have it explain step by step by a practitionner. Etc.. Having an animation perhaps to visualise the flow through the silver thread while doing spinal breathing...
Maybe having it divided into a series like "Beginner", "Advanced" and so on, the latter going through kechari and others, with some nice anatomical drawing, an animation perhaps of the tongue going up...
It could be fun and the proceeds could go towards the Starving Yogani Fund or something:)
