The Humble Look of Karma

Karma is something that sometimes scares me but at the same time, I feel that it needs to be taken a certain way. It's a bit like walking on an icy patch: if I know that I don't necessarily have the best shoes to walk the path and can never be 100% immune to slipping, I will tread more carefully and with a contrite heart. I am never at the point where I am completely "indestructible" or immune to the dangers or risks of life. It's important to cultivate a mindset that knows that everything we cultivate has a deeper effect on things around us.
  That having been said: it seems a bit mistaken to go the other way and make it one's life goal to accumulate karmic "points". The reason for this is that it solidifies a sense of self that stands to benefit from good karma. Heaven is created when I manage to convince myself that my deeds have protected me from the suffering of human life, and I am able to advance to a new place which is free of cares. But this state doesn't last. In fact, one of the deepest sources of suffering is how much of the karma we create which we consider as "good karma" is not meant to last. It needs to be renewed with new actions all the time.
   Can karma sometimes look like a treadmill? If one's purpose in life is only to accumulate good karma then, yes, life is a treadmill. But if, on the other hand, one can see that there is no discrimination of good and bad, then one has seen beyond the treadmill into something that is closer to the original mind. This is true relief, because then my life is no longer being over-run by ideas about good vs bad. While karma is important, it's only insofar that it helps liberate a person from the wheel of suffering that it makes sense. Otherwise, it becomes a game where one can't backslide even for a moment from accumulating karmic deeds.
