SB 11.13.12

rajas-tamobhyāṁ yad api
 vidvān vikṣipta-dhīḥ punaḥ
atandrito mano yuñjan
 doṣa-dṛṣṭir na sajjate
rajaḥ-tamobhyām — by the modes of passion and ignorance; yat api — even though; vidvān — a learned person; vikṣipta — bewildered; dhīḥ — the intelligence; punaḥ — again; atandritaḥ — carefully; manaḥ — the mind; yuñjan — engaging; doṣa — the contamination of material attachment; dṛṣṭiḥ — seeing clearly; na — not; sajjate — becomes attached.
Although the intelligence of a learned person may be bewildered by the modes of passion and ignorance, he should again carefully bring the mind under control. By clearly seeing the contamination of the modes of nature, he does not become attached.
