Wonderful for meditation
I have tried so much meditation music and spent tons of money on it. This is it for me nowadays and I use this daily for 1-2 hours if I have the time. It will balance your energy centers and I have actually felt it happening in my heart and in other places. I have had visions of different lights and see frindly faces a lot passing by (or scenery), a giant beautiful tree etc (the visions should not be hold on to because they are distractions for deeper meditation). Still, the visions and how I have felt the energy in different chakras is thanks to David Ison's music since I had almost no success going deeper and forward with other meditation music. Give it a try for some week and start with 30 minutes for a month....then 1 hour etc. The visions and energy feelings aren't the most important - they are just pointers that you are progressing some. Thoughts and distractions will melt away.
Best of luck :-) // Chris
