I met Sadhu Janagiraman at a function last night. He put forward a question: Given a tumbler of milk, an earthen lamp, a wick and a match, how do you light it up? He went on to give a beautiful explanation comparing the process that is required first to convert the raw milk into the finished product that is ghee in order to light the lamp, with the process of conversion and transformation that is required in us to attain the state of Jhothi.
