good point. i agree. Holosync is just too passive for me. although, people can practice active meditation (e.g. visualization) while listening to it. heck, we can even do vipassana as we listen to the sound

in general, i think Holosync is a good training wheels. but over the years i've learned and appreciated that the age-old techniques of meditation (specifically samatha+vipassana) is the real deal when it comes to liberation-technology. hey, it's free, open source, and belong to the commons
