Probably depends on what you want to achieve with meditation. My goal was to achieve things written about on this page: http://psipog.net/
Most actively I was going after clairvoyance.
And it worked to an extent, I eventually stopped because I couldn't distinguish what my mind was thinking it was doing from any sort of actual physical effect and I never managed to achieve anything that couldn't adequately be explained as lucid REM.
