A very interesting and informative post indeed.

I have heard of cannabis and Yoga I believe @jeffberwick practices this. Your right yoga is a developing world you move through the stages, I love kriya yoga. I will look into trying sativa yoga once I've found a good source. I gave up years ago and find that today cannabis if so modified its ridiculous. So I would like to find some natural untampered stuff to use, a difficult task these days.

Thank you for you information I await more :)
