Pipe smoking for the original tobacco smoking piper smokers was founded in both the spiritual and religious. Black Elk, in Black Elk speaks makes this abundantly clear. The only rule violation I can see is if one were to push a conversation on others that criticized, provoked, pushed, or poked another smoker's beliefs. In the public schools, teachers can freely refer to religion in the historical context of a discussion (although common belief is that they can't). For our purposes, whether one is reading while smoking either the Bible or Zen, and the Art of Motorcycle Maintenance, the context is spiritual. The discussion isn't about the Bible or the Tao per se, but the spiritual experience one might feel and experience while smoking. For example, those who use DMT almost always refer to it as a spiritual experience.
Clearly, not everyone sees smoking their pipe in this manner. That's not debatable; but just as clearly, many do. The purpose of this thread is to provide a space for those people who do find smoking to have a deep meditative or spiritual connection to pipe smoking to discuss this aspect of pipe smoking.
We talk about all aspects of pipe smoking on this forum: Cleaning pipes, buying pipes, maintaining collections, evaluating aspects of pipe construction, etc. For many pipe smokers, contemplation and a connection to something ethereal is just as important.
Tobacco, chemically, lends itself to this aspect of humanity. To shield a discussion about this aspect of smoking (clearly, most posters do not want to do this) from being discussed would be disingenuous and counter productive. It would be like having a discussion about running and not talking about the runner's high. Anyway, I am and have been enjoying the many thoughts that have been shared here. Let's hope that pipe smoking never succumbs to the politically correct in our own den of discussion. It's hard enough as it is.
