Step-by-step explanation:
When I was young, one of the many rules I had to follow was about not touching certain people. One day, out of curiosity, I touched a lady scavenger. My grandmother saw me and was so scandalized at the "sin" I committed that she fed me cow-dung, sand, and Ganges water to purify my soul. Years later, I saw a young boy left to die in the rain after being gored by a bull. Nobody took him to the hospital because he was an "untouchable."
Those incidences made me challenge our system that rewards an honest day's work - cleaning latrines - with scorn and humiliation. I joined the Bihar Gandhi Birth Centenary Celebration Committee in 1968 because I wanted what Gandhi himself wanted - to bring back the rights and dignity of the "untouchables." One problem he had, though, was that no technology could yet replace the bucket latrines, which required scavengers for cleaning. That's why I developed the Sulabh toilet, biogas digester, and other technologies.
