About 6 months ago, when I 1st discovered Dharma Overground, I found (I thought I did) several posts/posters referencing use of Holosync, a binaural beat listening program alleged to facilitate and accelerate deep (samatha-like) meditation/concentration. Later I looked back and only found one person referencing their use of the system. It seemed the person was having a positive experience.
I was intrigued. With some trepidation, and after researching it, pro and con, on the internet, I have embarked on the program. I'm about 3 months in and I like it very much--noting some potential drawbacks along the way.
I am looking for feedback from people in this community who are actually using, or have used Holosync. Pro or con.
For those not familiar with it, forgive me for not explaining it further--I don't want to advocate, or not. Much information, pro and con, is available online, if you are interested.
Briefly, what I see as good is a deepening of my concentration practice and ability to hold concentration better and longer while listening to holosync and also while not listening...Also, I look forward to holosync sessions more than previous practice without it.

What concerns me is overly aggressive marketing strategies, email galore, once one is involved and the blatant new-agey 'get rich quick and be more attractive' spin in the mix. The creator is Bill Harris, who is one of the people involved in "The Secret" blitz. Sigh.
I just wanna meditate better--the cd's really do help.

Thank you in advance if you have experience with this to share.
