Sastry but not a poet- Sanskrit sloka from Kavyalankara

अधनस्येव दातृत्वं क्लीबस्येवास्त्रकौशलम्।

अज्ञस्येव प्रगल्भत्वमकवेः शास्त्रवेदनम्॥

The knowledge of Šāstras possessed by one who is not a poet is like the pauper ' s charitableness , the eunuch ' s dexterity in arms , and the fool's self confidence
