Ramayana 4.51

"Whate'er a friend most wise and true, Who counsels for the best, should do, Whate'er his gentle part should be, Has been performed, dear friend, by thee. Taught by thy counsel, O my lord, I feel my native strength restored. A friend like thee is hard to gain, Most rare in time of grief and pain. Now strain thine utmost power to trace The Maithil lady's dwelling place, And aid me in my search to find Fierce Ravan of the impious mind. Trust thou, in turn, thy loyal friend, And say what aid this arm can lend To speed thy hopes, as fostering rain Quickens in earth the scattered grain. Deem not those words, that seemed to spring From pride, are false, O Vanar King. None from these lips has ever heard, None e'er shall hear, one lying word. Again I promise and declare, Yea, by my truth, dear friend, I swear."
