Theres a huge difference i can see, in that Dianetics/Scientology views the "reactive mind" (what I would call the animal soul) as a 'BAD THING' which must be negated, or at least countered, by using the analytic mind ( the intellect). It seems almost identical to the medieval christian beliefs which lead to witchburnings.
In my experience, meditation is far more open and accepting of the animal soul, not repressive of it. You may say our society is immature in how it deals with our animal nature --either by appealing to it salaciously thru advertisement, or by trying to deny it/villify it thru a religious revival, ----but at least we dont try to erase it, as dianetics does. I mean, isnt it clear the 'reactive mind' is also responsible for very important things like: individual thought, self-preservation, etc. What happens when you try and erase that? Wont you tend to make a person more weak-minded? More easily brainswashed than not?
Meditation is more open and accepting, IMO, of the animal mind in that you allow these thoughts/feelings to arise naturally and you accept them as part of yourself, not as something alien or foreign to you.
When you start to demonize a part of yourself (especially the primal part which keeps you alive) then you are doomed to domination by those who dont have your best interest in mind. Thats my opinion. :angel2:
