...so you're qualified to make that sort of statement? Got any publications to back it up for example? Concentrating on something for a cumulative 10 hours and 45 minutes is actually not uncommon in the slightest. Does everyone who focuses on something for that long disassociate? Or just people who focus on their breath? Why is it that good posture and focusing on one's breath in particular would cause 'disassociation' if that's your claim?
Maybe you go through life constantly asserting and believing things that are in no way true....with no experience nor credentials nor having even read any literature to back any of them up...
