SB 8.6.24
yuyam tad anumodadhvam
yad icchanty asurah surah
na samrambhena sidhyanti
sarvarthah santvaya yatha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
