In a mystical sense no, but in a practical sense yes. If you do something good that at the time seems like it has "no inherent reward" - you just do it because it seems like a good/kind thing to do - you'll often find that somewhere down the line it does actually "pay".

Or in a workplace for example, gain a reputation as a friendly/helpful co-worker and you'll find that other people are MUCH more likely to be responsive/helpful when you need the same. And vice versa.

So in that sense yes.
