This blog has become a sort of personal-cum-public diary. As for its contents, some are meant for me and my friends and relatives; others are for the public. This blog will have only positive, ennobling, elevating, encouraging and uplifting thoughts/ideas/materials. Whoever visits should feel happy and should be able to pick up some good ideas/thoughts/links. In short, "NOTHING NEGATIVE" is my motto.(Grateful thanks to Jon Sullivan and Public-Domain-Photos.com for the background photo)
