NEW DELHI, Jan. 30 -- I was reading the lovely book of Rabindranath Tagore's Gitanjali when a friend came in with a movie about Man's Flight in the Sky. He began playing it and expected me to join him. I found him rather interested in it. But I could neither give full attention to my book nor watch the movie on the screen.

Another friend invited me to a dinner with the cuisine prepared by him. As we sat at the table, his friend came in and screened a scientific movie about Charles Darwin's theory of Evolution. I could neither relish the tasty dinner with pleasant talk nor could I enjoy the movie.

We should give attention to one thing at a time. But today we are in the epidemic of multi-tasking, unable to concentrate on a single thing....
