Śrīmad-Bhāgavatam · Text 10.51.46
Who is speaking and story frame
लब्ध्वा जनो दुर्लभमत्र मानुषं
कथञ्चिदव्यङ्गमयत्नतोऽनघ ।
पादारविन्दं न भजत्यसन्मति-
र्गृहान्धकूपे पतितो यथा पशु: ॥ ४६ ॥
labdhvā jano durlabham atra mānuṣaṁ
kathañcid avyaṅgam ayatnato ’nagha
pādāravindaṁ na bhajaty asan-matir
gṛhāndha-kūpe patito yathā paśuḥ
That person has an impure mind who, despite having somehow or other automatically obtained the rare and highly evolved human form of life, does not worship Your lotus feet. Like an animal that has fallen into a blind well, such a person has fallen into the darkness of a material home.
