Hello I have heard that one of my colleague's friend has gone insane after her transcendental meditation practices. Have there been other instances of losing sanity with TM or other forms of meditation. I sometimes listen to CDs of meditation for relaxation and for good sleep, but I worry about the detrimental effects this kind of music may have on my mind? I'm looking forward to your informatory comments. Thanks in advance. Regards Sencan Topaloglu
