There is no you. What’s happening is happening effortlessly: the feelings and the thoughts. You can’t make yourself be happy because there is no you. There is just happiness or sadness or anything else. It all occurs without any effort. It’s not possible to figure it out because there is nothing to figure out.
Even the struggling: that’s what’s happening, and it’s happening effortlessly. Even the thoughts and feelings that someone is doing something wrong: those are what’s happening, and they’re happening effortlessly.
