Yes, I agree.
The real sorcerers of old times only ever used power plants rarely, like on a one off, to show apprentices that the spirit world exists, I.e to get them to experience a heightened or psychic state of awareness (a point of perception).
And then they would get them to practice many meditative techniques to halt the alien thought-form from monopolising their minds.
Power plants like all drugs are very taxing on the body, they use up your jing reserve energy, and blast open the chakras, making them easy to be infiltrated by the thought-form parasite. This is why people sometimes get possessed when drunk or high on drugs or power plants. I know because it happened to me a few times.
Today- all these people calling themselves shamans are opening people up to the spirit world, and because the shaman themselves is really only in it for the money, their heart is not pure, they have no problem letting the parasite come into the ceremony, because they are already part of, and working for the parasitic hierarchy.
They do not hold space, because they are already possessed by the alien thought-form. These people are not healing, they are all just getting high and getting slowly possessed, but of course they won't admit it!
Real sorcerers, those with integrity and real knowledge, are extremely rare.
