girija prasad, That is your really a bad thought. Lets make an example. Why don’t you meditate or ask someone to meditate during the day at your home or your friends home, eat all night, you can go to bed, if you do not like to bed, go back to your meditation after you eat in the night time. But make sure you do all day meditation without going to restroom and without eating anything, just the day time. But night time you can go to the restroom. Do this for a week. I can guarantee that your are going to get sick. Not only you any of us can get sick very easily. Now you are talking about this guy? Even though he is only doing during the day, still is a big sacrifice for him. I am 100% believe what people have said on that video clip. Please, please, do little bit more research and talk to others, otherwise you will look as a bad thinker.
