We are pleasure addicts. Freud talked about our existence being split between the pleasure principle and the reality principle; the reality principle is continuously frustrating our desire and our sense of self-definition, which is wrapped up in our addiction to pleasure. Obviously what is pleasurable for each one of us is different, but we seek it, and that seeking defines us. The pleasure that we seek is the pleasure that the Buddha casts off for the sake of another kind of pleasure—a pleasure that is not about the senses. It’s important to understand that thought is also a pleasure sense—probably the most effective. Each one of us has habitual thought patterns that give us pleasure, and this pleasure is powerful enough that we’re willing to sacrifice our life for it: time and again we choose our habititual thoughts over the expression of life itself.
