What is "excessive" meditation? People die after playing video games for 16 hours, but no one is going to argue that playing them for a couple hours a day is physically dangerous. I generally think the "meditation sickness" is more scare than substance, without much evidence for a causative link, but I think it's possible in certain circumstances. For example, I've heard of inexperienced people (i.e. people who've taken one hatha yoga class) going on week-long retreats and having negative experiences (including temporary psychosis and anxiety disorders) but that's not what I'm talking about. That's about as irresponsible as for an overweight person who can barely walk a mile to try out for a marathon. I think that a lot of "meditation sickness" comes from people who are prodromal of some sort of psychological crisis and (because of their increasingly difficult mental state) become interested in altering their consciousness, and that the psychotic break was not caused by the meditation but would have happened anyway. I can't prove that, but it's been my suspicion for a long time. For those who might argue that meditation is therefore bunk because some people who meditate end up getting frank mental illness anyway, my counterpoint would be that it's foolish to expect that a novice meditator can meditate his way out of a potentially physical mental illness; he needs medical help. What is very dangerous is when people try to use meditation or yoga in lieu of other well-tested, scientific medical treatment, which some New Age types believe in even though most actual meditators and yogis advise strongly against it. I talked to a very accomplished yoga teacher about using meditation to treat panic disorder (didn't want to use benzos) and he said, "Meditate, but see a doctor and take his advice. You can't meditate your way out of this, right now, any more than a person with heart disease can meditate out of that."
