During the mangala arati announcement, I could not hear the quote today because of some issue with the broadcast.
“Chanakya Pandit says that if there is one tree in the forest producing nice aromatic flower, that one tree can glorify the whole forest by the flavour of its flower. Similarly, if there is one tree in whose cavity there is a little fire, that one tree can burn into ashes the whole forest. So this simile is applicable anywhere. In a family if these is one good boy, he can glorify the whole family and similarly if there is bad boy he can turn the whole family into ashes.” — Tokyo, August 25, 1970
