Over ten years back, when I was in college, I was part of a group of students who wanted to do something for the society. The group led by one of my friends, Srinivas, did quite a lot of charity work, upliftment of underprivileged sections of the society, and educational work, and the group continues to do so. The group is a government-registered trust called DIYA today carrying on with all the philanthropic work with the help of a few good members.
