You Reap What You Sow

...or cause and effect...or Karma. Our intended actions will bear fruit, and we should judge our actions on the long term impact that such actions have. Our actions should not cause suffering to ourselves or others as the fruit that results from this is rebirth in a lower realm as in the worst case or unhappiness in less severe cases. I still struggle with the idea of rebirth and the different realms of "being", but it's much easier to agree that wholesome actions that benefit oneself and others result in a more fulfilled life now and if that just so happens to lead to a better rebirth then do I need to worry too much about such ideas?
