मुद्रराक्षस - भृत्या नृपतेः

अप्राज्ञेन च कातरेन च गुणः स्याद्भक्तियुक्तेन कः
       प्रज्ञविक्रमशालिनोऽपि हि भवेत् किं भक्तिहीनात्फलम् ।
प्रज्ञाविक्रमभक्तयः समुदिताः येषां गुणा भूतये
       ते भृत्या नृपतेः कलत्रमितरे संपत्सु चापत्सु च ॥

If servant is very loyal, but neither intelligent nor brave then he is of o use. If he is both intelligent and brave but lacks loyalty, then again he is of no use. Only those servants who are loyal, courageous and intelligent are the real reasons of a kings prosperity. The others are only playing supporting roles at all times.
