Krishnan was an award-winning chef with Taj Hotels, Bangalore and was short-listed for an elite job in Switzerland. After witnessing a distressing incident in 2002, he quit his job and began feeding the homeless and mentally disabled in his hometown. He said, “I saw a very old man, literally eating his own human waste out of hunger. I went to the nearby hotel and asked them what was available. They had idli, which I bought and gave to the old man. Believe me, I had never seen a person eating so fast, ever. As he ate the food, his eyes were filled with tears. Those were the tears of happiness.”
Krishnan founded the Akshaya Trust organization in 2003, which helps to feed the homeless and mentally-disabled in Madurai, Tamil Nadu. He serves breakfast, lunch and dinner to 425 indigent and elderly people in Madurai.
