Eric MacDonald wrote a beautiful piece about his wife and their journey to commemorate the fourth anniversary of her death (which is tomorrow). The piece is incredibly powerful and made me almost tear up a few times. He talks about love and loss, and it is just so beautiful. I think that he shows quite well that you don't need God, religion, or any metaphysical baggage to experience love and compassion. Our lives have meaning, beauty, and wonder without the need for anything inherent. He also shows that religious dogma gets in the way of compassion by influencing laws that do not allow people to get the help they need to end their suffering.
Just read and experience the love that he obviously felt for his dear departed wife. Experience the sorrowful beauty that it holds.
