Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 24
Sanskrit:
यूयं तदनुमोदध्वं यदिच्छन्त्यसुरा: सुरा: ।न संरम्भेण सिध्यन्ति सर्वार्था: सान्त्वया यथा ॥ २४ ॥
ITRANS:
yūyaṁ tad anumodadhvaṁyad icchanty asurāḥ surāḥna saṁrambheṇa sidhyantisarvārthāḥ sāntvayā yathā
Translation:
My dear demigods, with patience and peace everything can be done, but if one is agitated by anger, the goal is not achieved. Therefore, whatever the demons ask, agree to their proposal.
