Ramayana
ये च तत्र महात्मान ऋषयो ब्राह्मलौकिकाः । ब्रह्मणा समनुज्ञाता न्यवर्तन्त महौजसः । उत्तरं श्रोतुमनसो भविष्यं यच्च राघवे ॥ 7-98-24 ॥
And those great-souled sages who were there, dwellers in Brahma's world, men of great might, being permitted by Brahma, departed, their minds set on hearing the Uttara, the future that concerns Raghava.
