We have three operational centres: Mind thinks, Heart feels, Body acts. We know this because they change. (We cannot see what does not change.) After waxing and waning, the centres shut down. This does not affect us.
Our thoughts and feelings are completely unbidden. We don’t say, ‘Now I’m going to worry for 20 minutes,’ and then do just that. Our thoughts and feelings cannot be controlled. They happen to us. And then something untoward occurs. We get attached to them.
