Uma's example was a splendid one.. All it takes is a bit of encouragement from us to the next generation(it could be our friends, their children or relatives).. If you have children & relatives, follow Uma's example and take them to interesting places and show them and tell them about the wonderful things that happened at those places..
That way we will all be making our contributions however small, but still its a seed that will grow.. As bharathi says.. agni-kunju ondru kandaen, ..
We just need to light it up and see it grow and flourish.
