"One of the most powerful thoughts people have is the thought of necessity. It is much more than a thought. The word 'necessary' means 'it cannot be otherwise', and the Latin root means 'don't yield'. It suggests the emotional-physical stance of resisting, holding. That's the other side of the reflex system: when you say 'it cannot be otherwise', in effect your'e saying: 'It has got to be this way. I have to keep it this way'. You have a hold. Something that is necessary is a very powerful force which you can't turn aside. You may say 'I have to turn it aside.' Thus we establish an order of necessity, saying 'this turns aside for that, and this for that.'"
