That premise in 'The Secret' is really disturbing--
it's trying to take LoA and apply it to EVERYthing in a blanket fashion, which disorts it and puts it where it shouldn't be
LoA, like many principles, works in SOME instances, but certainly does not explain everything. There are definitely other forces at work in the world to explain many of those situations, NOT LoA.
another related, and very disturbing suggestion from a writer/ 'medical intuitive' named Caroline Myss, who said that those with diseases are suffering because of bad karma. She related a story about a young boy taken to a mystic by his mother, who was told that the boy committed some wrong in his past life, and was suffering now because of it.
This is SOOO wrong and a very dangerous claim to make (it totally turned me off of her writing, which has quite a negative style anyways).
I think many writers, either in science, religion, spirituality, etc, like to take THEIR principles from THEIR field and try to apply it to explain EVERY situation or phenomenon in the world. It doesn't work like that. There are many forces and laws, in each dimension, physical, spiritual, that are govered by laws of science, logic, or spirit, etc.. that work on different levels. When we're learning about what principles govern what situations, we have to learn to find the balances between the information that is coming from each source.. (and try not to be offended by the extremists with distorted information.)
