Śrīmad-Bhāgavatam · Text 11.20.5
Who is speaking and story frame
गुणदोषभिदादृष्टिर्निगमात्ते न हि स्वत: ।
निगमेनापवादश्च भिदाया इति ह भ्रम: ॥ ५ ॥
guṇa-doṣa-bhidā-dṛṣṭir
nigamāt te na hi svataḥ
nigamenāpavādaś ca
bhidāyā iti ha bhramaḥ
My dear Lord, the distinction observed between piety and sin comes from Your own Vedic knowledge and does not arise by itself. If the same Vedic literature subsequently nullifies such distinction between piety and sin, there will certainly be confusion.
Read the purport on Vedabase.ioFrom Canto 10, chapter 14 onward, the translation and purports were completed by Śrīla Prabhupāda's disciples after his departure, and published by the Bhaktivedanta Book Trust.
