Sri Chinmoy: Although their concentration is in the physical plane and the vital plane and not in the psychic plane, still it does help. It is a power, like money-power, which can be applied to any purpose. But if you want to buy something subtle, with money-power you cannot do it. For subtle things you need a different type of concentration.
There is a great difference between psychic concentration and physical or vital concentration. Psychic concentration is really difficult — much more difficult than physical or vital concentration. It is like the elder brother. But the younger brother can definitely help the elder brother. The concentration-power that you learn from athletics will definitely add to your psychic concentration. And if someone has psychic concentration as well as physical concentration, vital concentration and mental concentration, then that person can easily be a great champion in the athletic world as well as in the spiritual world.
