No. I referred to everything up to and including death (although karma is not limited to what happens in a single lifetime).
Karma is about the future: the results of deeds. But to try and separate the now from the future is problematic. "the reality we currently occupy" is not sufficient to understand karma. Karma relates to the whole, the entirety.
Well then, I guess as a random, intellectual exercise in futility, one that doesn't make sense If there is no start, no end, (i.e., no boundaries) then how could there be a whole? The entirety of the concept relies on one being willing to suspend belief in all tangible evidence of the world.
I would be willing to accept the concept that no one is necessarily more important/has more meaning intrinsically than anyone else, at least as a whole. In some given circumstances, someone's importance could outweigh some other's (e.g. the surgeon in the operating room).
However, it comes back to perspective. If there is no beginning, no end, no consequence or importance to anything, then there is also no reason to do anything other than fulfill biological imperatives. It also suggests no reason not to act on impulse, to simply go after whatever one desires, regardless of how it may affect others. Since there is no end game, no goal, no actual purpose, it could not be else-wise.
You said, "Karma is about the future: the results of deeds." This statement implies cause and effect. Yet if it is both,(cause and effect) then it is neither as well. If it is all, and it is nothing, then the point, is pointless. (I'm truly not meaning to come across as glib here.)
I'm not saying that how you are expressing what the idea of Karma represents is wrong (as in definition of the word, I'm sure you are far more informed than I am), what I'm saying is that, if it is how you are stating it (we have no importance, we have no beginning or end which implies infinity/eternity to alter choices, which would be hard to do as we take "nothing" (broad meaning word) including experience, learning, etc.) with us into some possible next life, then individual lives have no value, the "current reality", the one as experienced by the body and brain we inhabit while we have this conversation, is pointless. And since, even the "God" referenced in an earlier post in the thread, other than having "created" everything on a whim, has no interest in it either, why bother?
The basic idea, which as a westerner, and I know is not a correct or at least complete analogy, is that Karma is like, "what goes around, comes around". I think that people having heard that, is what prompted the comparison to the "Golden Rule". Those two ideas, at least have some bearing on the "here and now". If Karma, does not, what does it have to do with?
This has been incredibly long winded and I apologize to everyone for my inane prattling while trying to come to grips with this.
