Sedona any day even tho I've only got the book The power of letting go by Patricia Carrington.
Although it depends upon what you're after.
I've used holosync + paraliminals and they don't always cause greater effects. Sometimes there's nothing. I've actually stopped that project. It seems like the power of intention is far more important than going down a level in your mind before listening.
Holosync causes tension, more and more after each level, not on specific things. Sedona makes you ask yourself some important questions. Can I let go of wanting to control x? Can I let go of wanting to protect x? Can I let go of wanting approval from x? Essentially. Perhaps all you need is a book or you want a complete course.
If you want an inexpensive Holosync-alternative. Perhaps you'd like to try Insight from www.awakenedminds.com I don't know about long term use but it seems effective to me. I've used both Holosync and Insight. I'm a newbee... The price is right for one of the products.. I have no way of knowing about long term changes/effects.
Cya!
