Q: Is it possible to live without food?
Yes, it is. When I did my fast of about 23 days, while living in Chettiar’s house, I very nearly solved the problem.
I could walk eight hours a day as usual. I continued my mental work and Sadhana also as usual and I found that I was not in the least weak at the end of the fast. But the flesh began to grow less and I did not find a clue to replacing the very material part that was reduced in the body.
When I broke the fast, then also I did not observe the usual rule of people who go on long fasts, of beginning with little food and so on. I began again with the same quantity as I used to take before.
