Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 8

Sanskrit:

एतद् विद्वान् मदुदितं ज्ञानविज्ञाननैपुणम् ।न निन्दति न च स्तौति लोके चरति सूर्यवत् ॥ ८ ॥

ITRANS:

etad vidvān mad-uditaṁjñāna-vijñāna-naipuṇamna nindati na ca stautiloke carati sūrya-vat

Translation:

One who has properly understood the process of becoming firmly fixed in theoretical and realized knowledge, as described herein by Me, does not indulge in material criticism or praise. Like the sun, he wanders freely throughout this world.

Purport:

Every living entity emanates from the Supreme Lord and is thus naturally full of realized knowledge. But when one becomes attached to praising or criticizing material good and bad for one’s personal sense gratification, one’s expert knowledge of the Lord becomes covered. A pure devotee should neither love nor hate any aspect of material illusion; he should rather accept whatever is favorable for serving Kṛṣṇa and reject whatever is unfavorable, following the guidance of a bona fide spiritual master.
