There are many in this world who may not be in physical pain but suffer with mental problems. I would venture to guess that most of the suicides in our society are the result of these mental disturbances. Those who see the world through the jaded lenses of psychological afflictions are also in need of curing. For these people a trust needs to be placed in our modern day psychologists, who will hopefully will show them the source of their subjective conditions. I also understand that many mental afflictions are the result of chemical imbalances, which hopefully can be treated with drugs or perhaps light and/or sound therapy (which are sciences that hold much promise today). Mediation is another form mental purification, though in todays western world I would be surprised to find a psychologist who would subscribe such a healing.
Actually a lot of psychologists prescribe meditation or mindfulness - my current one does and there is a mindfulness program at our local psych hospital but it is not well attended and it is not offered to mood inpatient consistently which is unfortunate. Even the private inpatient program I did made you do four sessions of mindfulness but most people didn't do a fifth. Part of it is that it's hard to convince people whose brains are either on fire or so depressed that they can't hook in. It almost has to be a mandatory thing and set up in a no-fail environment. I'm not sure many psychiatrists though would prescribe it (if one could even see one in most Canadian cities). It really does help and even though I know it, I have a hard time acessing - part of the trouble with mental illness.
