Shatakatraya 1.51

1.51

re re cātaka sāvadhāna-manasā mitra kṣaṇaṃ śrūyatām
ambhodā bahavo vasanti gagane sarve 'pi naitādṛśāḥ |
kecid vṛṣṭibhir ārdrayanti vasudhāṃ garjanti kecid vṛthā
yaṃ yaṃ paśyasi tasya tasya purato mā brūhi dīnaṃ vacaḥ ||

O cātaka, friend, listen for a moment with attentive mind: / many clouds dwell in the sky, but all are not like this; / some moisten the earth with showers, some rumble in vain; / do not speak wretched words before whichever one you see.
