The king should never engage in idle disputes. He should never cross a river with the help only of his two arms. To eat cow-horns is useless and never gives strength. By eating them one's teeth are broken while the taste is not gratified.
न शुष्कवैरं कुर्वीत बाहुभ्यां न नदी तरेत्। अनर्थकमनायुष्यं गोविषाणस्य भक्षणम्। दन्ताश्च परिमृज्यन्ते रसश्चापि न लभ्यते॥
