A tradition in India is to celebrate one's birthday by feeding the less fortunate. Indians often donate rations (rice, dahl, etc.), or money for meals, to orphanges on their birthdays.
Last week, one of the rickshaw drivers in Mysore brought his mother to Karunya Mane on her birthday, as she expressed the desire to celebrate her day by giving our kids cake and other goodies. He brought his son and wife, along with his mom and dad.
