Blame was the last thing on my mind when I wrote my comment. I was merely trying to provide some suggestions that would maximize the odds of having a productive experience and good integration afterwards.

Yes, things could go wrong even if one takes every reasonable precaution, is in the best frame of mind, etc. That's why having helped from experienced people you can trust is a good idea, but even that offers no guarantees.

There are no guarantees in life for anything. You could break your neck climbing a ladder to change a lightbulb. People can and do suffer severe accidents (including severe brain damage) skiing, driving, or crossing the street.

Yes, you should be aware of the risks and look both ways when crossing the street, but you could still suffer some accident even then. For some the risky activity is worth it, for others not. For those who think it is, it's helpful to educate oneself and take reasonable precautions. No blame necessary or intended.
