This is the best thing to maintain one's relationship with other fellow humans, wonderful idea by the Genius @wwf <3
This thing is necessary to teach the masses how they can build a superb relationship for e.g husband & wife, Brother and sister, student and teacher, colleagues, street fellow, sportsman.
It is a micro level approach to make your bonding strong and pure with others. Great idea with pious intention. I loved it @wwf <3 <3
