I believe I am the poster you are referring to. Lets just make an amendment here; I never said Aikido was designed to free anyone from modern technology. I said overuse of technology draws us away from the source. The source means nature. And none of that had anything to do with cannabis; it was on a completely unrelated note. I agree that cannabis is a powerful medicinal herb, but I simply don't think using it for the sole purpose of altering your mind is a very natural practice, like you. And... it has many health problems.
I also agree wholeheartedly about the overuse of technology and the misuse of substances. The source is nature, and isn't amazing how little people understand about one of nature's most powerful substances, air. That's the beauty of Aikido and Kokyu power!!
