Think lightly not of goodness,
‘It will not come to me’,
for by the falling of water drops
a water jar is filled.
The sage with goodness fills himself,
he soaks up little by little.
Explanation: Some tend to think that virtue can be taken lightly, and that virtue practiced is not likely to bring about any spectacular good results. This view is not quite correct. The good done by an individual accumulates little by little. The process is very much like the filling of a water-pot, drop by drop. As time goes on, the little acts of virtue accumulate, until the doer of good is totally filled with it. Link source
