As a process, emotions always start with a thought – the thought comes first.
But when we come in and notice that process, we come in somewhere in between, in the train of the process. We might start noticing when there’s an emotion, or we might start noticing when there’s a thought. Subsequently, even though a thought starts the emotion, but the emotion feeds the thought. When we’re able to keep watching that process and not be involved, then the awareness starts becoming stronger while that process starts getting weaker.
