Nosebuds
I have a meditation-teaching site that works (I tried it) and hope it's all right if I share it with you guys, although I'm not a member of this guild.
www.silvaultramindsystem.com
It's a website with nine free lessons, including audio guides and such. Simple, doable, etc. etc. I found the excerises mentally invigorating.
No offense, but I won't add that link to my list. I stay away from websites that try to "sell" techniques to enlightenment and things like that. If the creator of the website were truley concerned about the betterment of mankind, all his lessons would be free.
He does provide a few free lessons, yes, but those are designed specifically to make you want more and buy his books and subscribe to his study program. That kind of thinking is a spiritual poison, and that is why I will not post his link in my list.
