kyzz; see some of my other posts. As to "conditioning of our choice", substitute the word "learning" if you like. You choose to learn some things(teachers expect you to learn other things). It takes practise/repetition to learn things. Anything you can do without thinking, you learned, even walking, etc. We also have the ability to learn instantly, without practise. Huh? you might wonder. Our involuntary automatically/instintively reacts to "perceptions", but there's a human trick, we can take advantage of that "proclivity" of our involuntary to react to perceptions. We simply "believe" some of our images are real and "bingo", our involuntary can't tell the difference and so reacts to our images. What a "cool" set up. Only we inadvertently, UNWITTINGLY believe some false images, so not only do we fool our involuntary, we even fool our selves, not recognizing our own 'trick', we attribute those reactions to environmental stimulus, another,self deception. I want you to 'deeply' understand using something already present. Like flying a kite, we utilize the wind. We humans utilize water flow in rivers. With a water wheel , the water turns the wheel, the shaft extended, with a belt turns 'devices' (before electricity) etc. Our involuntary already reacts to perceptions, so believe some of our images are real and we utilize it the way we utilize the wind and water. To date, there's a "catch", we can't just think I will believe a inert pill is medicine and take it and feel better, no, we have to be fooled , either by others or ourselves into believing what is not so. And how does that work? How do we mistakenly believe thought-images that don't match 'facts'?
You know the echo effect. We yell "Hello", and sound travels and 'bounces' back. Children can be fooled into believing another person, far off, is calling hello back. Here's the joke on us adults, we do the same thing by "unwittingly" believing our images are real, we react to them. That's more ludicrous than children believe there echo is real. Children don't suffer for their mistake, but we do when we believe some of our images are real.
