यशस्तिलक - धूर्त मंत्रि

चारो यस्य विचारश्च राज्ञो नास्तीक्षणद्वयम् |
तस्यांधदुग्धवद्राज्यं मंत्रिमार्जालगोचरम् ||

- यशस्तिलक

A king who does not have an elaborate spy network and a sane logical mind (for analysis) will lose his kingdom to the minister. This is the same fate that happens to milk kept in front of a blind man. The cat will silently drink it all.
