Here’s a free, online class in mindfulness based stressed reduction. Professionally produced, there is solid science behind these methods that show solid, tangible results in helping people have happier, more full lives. Includes instructions, guided sessions, and materials needed. Coursebook is optional.
This site has long been a favorite of mine.
The podcast meditations are brief, very well done and just, well, lovely.
Do yourself a favor and listen to a few.
