In the film, The Power of One,
P.K. and his professor discuss
The law against teaching blacks to read and write
P.K.: How will they ever be included if they can't ever read or write English.
St. John: I quite agree with you, P.K. But at the end of the day, it's only about a dozen people you're talking about teaching. How much difference will that really make?
P.K.: A waterfall begins from only one drop of water, sir. Look what comes from that...
