I agree with Jeff's recommendation. The Butterfly Meditation CD does indeed sound like a variation of the Self-concentration meditation. But vive l'differance!
It is my favorite of the variations on the Self-concentration model.
And since I can no longer edit my first message (you would think the system would allow editing of your message for a longer period), let me also correct "CMF" to "CFS", I was attempting to abbreviate "Chronic Fatigue Syndrome", but there was a detour somewhere in my brain path!
Shakurav gave a great description of Master Lin's meditation.
I recommend it (the CD) highly!
It reminds me of Self Concentration but even more beautiful!
