The basics will never change. As the good doctor keenly observed in HBP there are 2 pillars to healing. The first pillar is the acquisition of knowledge into the nature of the disorder, and the second pillar is acting on that knowledge. Those who heal get to pillar 2.
So the first stage is gathering the information, reading, listening, learning all about TMS and how the mental affects the physical. But at some point the sufferer has to stop gathering and start living (at pillar 2.) The incessant gathering, and desire to read more and more well past the point of current knowledge is TMSing, ie, the person is putting off the healing. It's a defense mechanism against healing (albeit unconscious). I call pillar 2 "letting go of pillar 1." You can't take the second step until you leave the first one.
Now--some people may not connect with the original source/info. I did, and still feel that HBP is all anyone ever needs. But I realize that it doesn't work for everyone, so I wrote GPD. But it too may not connect with someone, so they seek until they find that thing that pleases them. That's still pillar 1, and some may spend some time there gathering. It's ok, and not a bad sign. It usually takes a neutral person to point out to them that they're delaying the healing. This can be done by asking them questions about TMS, if they know it inside and out, pillar 2 is eagerly waiting to be stepped on.
