How many are there who can meditate and practice japa all the time? At first they earnestly practice these disciplines, but their brains become heated in the long run by sitting constantly on their prayer rugs. They become very vain. They also suffer from mental worries by reflecting on different things. It is much better to work than to allow the mind to roam at large. For when the mind gets a free scope to wander, it creates much confusion. My Naren (Swami Vivekananda) thought of these things and wisely founded institutions where people would do disinterested work. - Teachings of Sri Sarada Devi, the Holy Mother – Part 2, Vedanta Society of Southern California
