define "good". ?:|
Michael's free "Discover Meditation" course that you can download from here is good. It teaches meditation and there is plenty of support on these forums for any questions you have. And it's FREE so that's got to be good, especially when a lot of organisations and personal teachers will charge large amounts to teach you what is essentially the same thing (and perhaps fluff it up with a few bells and whisles whilst they're at it)
Is there anything in particular you are looking for?
