Excerpt from the book "The Four Noble Truths" by Luang Por Sumedho:
«If you love rational thought and are attached to ideas and perceptions, then you tend to despise the emotions. You can notice this tendency if, when you start to feel emotions, you say, 'I'm going to shut it out. I don't want to feel those things.' You don't like to be feeling anything because you can get into a kind of high from the purity of intelligence and the pleasure of rational thinking. The mind relishes the way it is logical and controllable, the way it makes sense. It is just so clean and neat and precise like mathematics - but the emotions are all over the place, aren't they? They are not precise, they are not neat and they can easily get out of control.
