On doing good

Our last trip was to McLeaod Ganj, the birthplace of Dalai Lama.
We went to a strange charity concert for Tibetian olymics.
The lead singer (he was something between Santa and a rock-dinosaour) told us the following.
Some years ago, he met Dalai Lama for the first time and started compalining that things are not going well, it is hard to try and change things in the american societiy and so on...
Then the Dalai Lama said:
You find it hard to go ahead, as you are doing good deeds.That is why u meet so many obstacles. If you were doing bad deeds, it would have been much easier.

However you should not give up doing good. Cause...what goes around, comes around.
