If you read the lives of the great workers which the world has produced, you will find that they were wonderfully calm men. Nothing, as it where, would throw them off their balance. That is why the man who becomes angry never does a great amount of work; and the man whom nothing can make angry accomplishes so much. The man who gives way to anger or any other passion cannot work; he only breaks himself to pieces and does nothing practical. It is the calm, forgiving, equable, well-balanced mind that does the greatest amount of work.

यदि वयं अस्मिन् प्रपञ्चे महतः कर्यसाधकान् परिशीलयाम: ते सर्वे विशेषतया प्रशान्त-स्वभावा:। किमपि तेषां सन्तुलनं भग्नं न करोति। अतः एव क्रुद्ध: मनष्यः कदापि महत्कार्यं कर्तुं न शक्नोति। केनापि कारणेन यः मनुष्यः कुपितः न भवति, सः किमपि साध्नोति। राग-द्वेष-क्रोध-ग्रस्त-मानव: कार्यसाधक: न भवेत्। सः स्वीय-विनाशं करोति। तेन किमपि प्रयोजनात्मकम् न क्रियते। शान्त:, समचित्तः, सन्तुलित-मनस्क: ,मनुष्यः एव बृहत्कार्यसाधक:।
