A few more superb excerpts from the book:
What’s crazy is that most people didn’t have any thoughts going through their mind when they felt the happiest and the most amount of love in their lives. For those that had the thought that they were grateful, they felt that way before having that thought. If they had that thought, it happened after they felt the feelings, so the thought could not have produced the feeling. This brings us to another truth: you do not have to have thoughts or think to feel positive emotions.
It is not the content of our thinking that causes us stress, but that we are thinking, period. The amount of thinking we have going on is directly correlated to the magnitude of stress and negative emotions we are experiencing at any given moment. When you’re experiencing a lot of frustration, stress, anxiety, or any negative emotions, just know that it is because you’re thinking, and the intensity of those emotions is directly correlated to how much thinking is going on. Therefore, it’s not WHAT we’re thinking about that is causing us suffering, but THAT we are thinking. To summarize, we do not have to try to “think positive” to experience love, joy, bliss, and any positive emotions we want because it is our natural state to feel those emotions.
