List of research sources: What is good?

Just wanted to post up some of the better research I found on meditation for anyone who is interested:

• www.eckharttolle.com
• www.falundafa.org
• www.tm.org
• www.nhs.uk/.../Meditationreducesstressandimprovesmood.aspx (you can navigate onto other meditation topic articles from here.)
• www.healthandyoga.com

they are probably the best reseources I have so far, but the hunt is still on!
