I vaguely recall reading somewhere in a book about Buddhist philosophy that thinking is the function of the brain, just as breathing is the function of the lungs. That's what it's physically designed to do. Neuroscience is helping us discover how emotions and thoughts are generated by living tissue, but it's a young field and there are a lot of unanswered questions. My guess is that OCD has organic origins, but that doesn't mean that there's nothing you can do about it. It may require medication, or it might require becoming adept at mental yoga (meditation). Keep in mind, though, that the various types of meditation described in the suttas were not designed to deal with OCD. On the other hand, if you consider OCD as an exaggerated 'monkey mind', that might help. Best of luck, Zack and BuckyG!
