If we recognize this fact, we can have compassion for ourselves as we react to circumstances in the way our history would predict. And we can change our patterns and the way we see things through our awareness and with practice, and more practice.
Before we can be the best that we can be, we have to understand why we do the things we do, and all of the ways that we have been conditioned to cope.
I learn about the way I am by the things that trigger me, and with compassion, and patience, I learn to be less reactive.
