Question: Sometimes when I start to run I get angry, even furious.Sri Chinmoy: See if you have had enough rest. Perhaps you are compelling the body to run, but the body is not cooperating because you have not had sufficient sleep on those days. You have a very mild and kind nature, so I think that you are not getting enough rest at night. Then the following morning you curse yourself and ask yourself why you are running. You need more rest to calm your nerves.
