Śrīmad-Bhāgavatam · Text 3.4.21
Who is speaking and story frame
सोऽहं तद्दर्शनाह्लादवियोगार्तियुत: प्रभो ।
गमिष्ये दयितं तस्य बदर्याश्रममण्डलम् ॥ २१ ॥
so ’haṁ tad-darśanāhlāda-
viyogārti-yutaḥ prabho
gamiṣye dayitaṁ tasya
badaryāśrama-maṇḍalam
My dear Vidura, now I am mad for want of the pleasure of seeing Him, and just to mitigate this I am now proceeding to Badarikāśrama in the Himālayas for association, as I have been instructed by Him.
