By not reacting you are free to create.
Once something is determined to be it becomes that. Even if it is not. It becomes that to you. A lifetime of self-deception is built up around it. The world populates that reality with all sorts of supporting evidence. Any reaction to the world is a reaction to the thought built up in the mind.
We now know through Epigenetics that 95% of behavior is drawn out; conditioned from an old reality. A reality that no longer exists, except for fragments from memory. The past does seem to get re-created all of the time. But what we react to is just a house of cards; an illusion. This is not new news, except for our modern iteration of society. With a deep inner-connection our behavior is not simply drawn out from old programming, but lack of awareness; ignorance.
