In the book "The Seven Spiritual Laws of Success" Deepak Chopra talks about karma. He says it's both the action and the consequence of the action. He goes on to explain that everything happening today is a result of past choices we've made.
Now while there are many project management analogies I could think of, the one that comes to my mind first has to do with relationships. How we have treated people in the past will impact our current and future situations.
Another book I'm working my way through is "never eat alone" by Keith Ferrazzi. This book stresses the importance of developing good relationships. The lesson for any of us is that by building good relationships now, we will have more opportunities for success later. Everyone we come across has something to offer us, we need to figure out what it is by taking the time to really get to know people.
