Perhaps for some of you this letter will be nothing new, but for me it was an aha-moment. I used to think that a thought is a thought, emotion is an emotion, a physical sensation is a sensation. And while thoughts and sensations were very clear for me and I could tell what was a thought and what was a sensation, emotions were kind of hard for me to explain or point at. They were like an ambiguous cloud that came on you and your clarity was lost for a while.
