Question: What is the most effective mantra for a runner?

Sri Chinmoy: God's Name is the most effective mantra for each runner. There are two ways to repeat God's Name: even if you are running a marathon, if you are inspired to repeat God's Name as fast as possible, then do it. Again, if you are inspired to draw deep breaths and very slowly and quietly repeat God's Name, that is also most effective.
