Even though this question was answered pleasantly and humorously by a lot of folks, my take on the question.... IF looking at it a bit more philosophically:
For me pipe smoking is a habit/hobby (or whatever preferred descriptor you choose) that has many roles for me.... enjoyment, nicotine, relaxation.... all of the usual things.... but, yes.... I do believe I sometimes do also use my pipe smoking as a tool to help me contemplate things, and yes, when I do try to foster more compassion in my attitude, my outlook, or my actions..... I will often smoke my pipe at least in part to a) give me some quiet moments to organize my thoughts and ideas towards being more compassionate, b) to have a “break” or “separation” from what was occurring earlier in the day so that I can perhaps feel and/or prepare to be a more compassionate person in an upcoming situation.
Now.... OBVIOUSLY a pipe is not required to be a contemplative or compassionate person.... but in thinking about the OP’s question..... I can say that I HAVE used the pipe as a tool to help me try to be both on a variety of occasions.
