Feelings are a given, they’ll always be there. To feel is human, but taking them to the next level to form concepts is when attachment arises as a belief the feeling needs to be different.
If it’s not learned to just be with the feeling that arises, it will control you. This is because of the conditioning of a mind that wants to push the feeling away and change it. How this works is, let’s say someone walks up to you and says something that you don’t particularly care for, immediately there’s attachment as there’s the feeling of not caring for what was said. And where there’s attachment, there’s the tendency to react the way you always react when someone says something that’s not cared for. This is done again and again because of the conditioning in place. Someone says something you don’t care for and you wind up saying something back to them. What you do is take their dissatisfaction and make it your own and then you throw your dissatisfaction back at them. Now basically you are at war.
Feeling aren’t right or wrong, there’s very little facts as to why they arise. The main thing is to allow their energy to remain free flowing so it doesn’t get bottled up and form a conditioned concept. These concepts are formed by attachment to mind patterns that change a simple feeling into a story; the story being the feeling needs to be changed. It’s not true the feeling needs to be changed, but that’s what the conditioned energy does, it makes you believe a feeling is unpleasant and a pleasant one would be better. This is energy that wants to push away when feelings arise because it doesn’t understand they aren’t right or wrong, they are just what’s there and you don’t have to attach to them.
