What is automatic cannot be you
Almost everything you think that you think (and say) is an expression of your machinery. It is almost entirely automatic. And what is automatic is not you.
Our machinery is a very important part of what we have
This doesn't make it good or bad. Much of our machinery operates in a way that gets us what we want and supports us in our life. But, because the machinery has come to believe some things that aren't true or helpful, we may find our machinery fighting with itself or fighting with the machinery of others.
Ways that our machinery creates suffering
For example, each of these automatic thoughts/speakings are expressions of the machinery at war with itself or others:
"I should work harder." (translation: my machinery thinks it should work harder and there is something wrong with other machinery if it doesn't work harder, even though what is "hard enough" is not defined)
"You never keep your word with me." (translation: my machinery mistakenly believes that you never kept your word with me and that blaming you is the only way it has to get you to keep your word with me more often)
"I have an obligation to my family." (translation: my machinery is not willing to feel the fear of the probable blame from my family and society, if I do not fulfill the commonly agreed upon expectations of my family and society)
These are just a very few examples of the thousands of toxic ways in which your machinery can impersonate you. And your machinery believes that it is you. But the machinery is automatic. Yes, it is your machinery, but it is not you.
But what are you, if not your machinery?
Let me point to a "part of you" that has the ability to observe and listen to your machinery with compassion and curiosity. That "part of you" also has the capacity to make non-automatic choices to take new physical and/or mental actions. These observations and choices will modify or replace the unresourceful beliefs and actions of your machinery, step by step and over time.
