Thanks for report.
This is also music i am listening. Best without ad. My schedule is also 20-30 mins.
I had panic attack problems in the past so everything makes me scared. There are tensions in my heart region of the body. I cant tell it is my heart rhtym or fake but it makes me stressed. I constantly tell myself or my ego calm down it is just feeling and those things are not real and they disappear. After experience i feel euphoria i can laugh a tv show like i am a child. But after a day or so something happens what leo call it ego trying to comeback. I been distracted easily. I cant work properly.
What i decide i should do it once or two in a week and keep going with meditation and concentration work daily. To my perspective 1-1.5 hours personal "spiritual" work is enough. I think ego started to change this spiritual quest to a "pleasure seeking" and makes it useless.
