Have regular hours of meditation. Meditation calms down the mind. It induces quiescence in the mind. If you meditate earnestly for one hour, even during remaining twenty-three hours, the tendency introduced by meditation in the mind persists and the mind does not oscillate as much as before. Gradually increase the period of daily meditation. This will not interfere with your daily work, because meditation increases your various faculties and gives you the capacity to turn out more work in less time.
