I talked with my supervisor today about my dissertation. I don't think he realizes it, and he'd probably laugh if I pointed this out to him, but he's a Buddhist. Everything he said to me can be summed up as the Three Characteristics:
unsatisfactoriness: There is no way to make this document perfect.
impermanence: No matter how good my measurement, how precise and elaborate my conclusions, someone else--probably, in my case, very soon--will do a better experiment.
non-self: It's not me my committee will be evaluating: it's just this document.
This last Characteristic is in a lot of ways the hardest to get one's head around--but it's liberating. The work I do is not self. The judgements other people pass are not self. The heart that grieves is not self. The body that dies is not self.
