Acts of kindness performed, not expecting any reward, compensation, praise, acknowledgement or good karma. Acts of kindness done because you want to, and most of the time, feeling good afterwards is the reward itself.
In the few rare instances, when people are happy as a result of your act, their happiness are multiple tenfold within you. The joy you feel, the spring in your steps, the rose-tinted world view, the smile on your face, all these will remain for a very long time. These are the best rewards.
