Ramayana
ससूत्रवृत्त्यर्थपदं महार्थं ससङ्ग्रहं साद्ध्यति वै कपीन्द्रः । नह्यस्य कश्चित्सदृशो ऽस्ति शास्त्रे वैशारदे च्छन्दगतौ तथैव ॥ 7-36-47 ॥
This lord of the monkeys masters the great-meaninged science complete with its aphorisms, its commentary, its glosses on word-meanings, and its compendium; for there is none equal to him in learning, nor likewise in skill in the movement of metres.
