No. It would require that there be some kind of core “me” that would get moved from one existence to another, and I don’t see anything in my own makeup that would qualify as this kind of personal essence. What, in other words, would be the “same” from one life to the next? Scarcely anything is the same from one moment to the next.
From what I can see, everything about me depends on factors that aren’t “me” in the conventional sense. Put simply, I am the way I am because everything and everybody else is the way they are. I may have a feeling of being a discrete and independent being, but that’s just a conceit caused by my inability to fathom how densely interconnected I am with everything else.
So everything that I do has some effect, large or small, on everything else, just as what anyone else does has some effect on me, whether I can perceive that or not. Each of us, by our actions, sways the course of our common flow. That’s the only way I feel that karma has any real or useful meaning. The interconnectedness of us all is such that it makes more sense to me to see us all as a single being: this common flow. That being will go on when this lump of flesh is gone, and I care about it and all the individuals flowing in it, because it’s our common sort. I don’t want, by my actions, to introduce painful turbulence into that flow; not because that will screw up my future life prospects, but because I love that flow.
