Hagbard,
I took a look at that preset you mentioned. I can certainly understand your reaction. Trying to entrance your brain to 80 some Hz seems strange. I don't think it is possible entrain at that frequency. Maybe high frequencies generate agressiveness like you felt.
Anyway, I am looking at some others and a few seem decent.
No seems to have tried using harmonics of the chakra frequencies. I am thinking it might be possible to activate multiple chakras at once.
Definitely something to try....
