I'm sure I have a Krishna Das meditation Cd, it's very deep and high vibrations. I do like to use it for a deeper meditation. The voices are very powerful and seem to take me on a stronger journey. I have used it in my group meditations but it's not everyone;s choice. I feel some people are more used to a lighter meditation, so I feel it depends on the type of people whom you use it with. :) love & light.
