No panic attacks in my experience. But plenty of stress and highly stressful events in my life. And only substantial value I got is a relaxation and calmness, some rest for the body and mind. But I might as well call it “self relaxation techniques” and ignore the whole meditation industry. So part of my question is - is there anything there except some common sense relaxation techniques?
