Franco Columbu: Are there yoga stretching exercises which benefit nerve conduction or nerve supply to the muscles?
Sri Chinmoy: Yes, there are some Indian asanas that can offer a fresh supply of energy to the nerves, and to a certain extent the muscle-power can be increased by taking these exercises. If one is interested in this, he can go to some Hatha Yoga experts who can demonstrate and teach those particular exercises.
