caranti hy avanau kāmaṁ
 brāhmaṇā bhagavat-priyāḥ
mādṛśāṁ grāmya-buddhīnāṁ
 bodhāyonmatta-liṅginaḥ
Synonyms: 
caranti — wander; hi — indeed; avanau — on the surface of the world; kāmam — according to desire; brāhmaṇāḥ — the brāhmaṇas; bhagavat-priyāḥ — who are also Vaiṣṇavas, very dear to the Personality of Godhead; -dṛśām — of those like me; grāmya-buddhīnām — who are obsessed with temporary material consciousness; bodhāya — for the awakening; unmatta-liṅginaḥ — who dress as if madmen.
Translation: 
Brāhmaṇas who are exalted to the position of Vaiṣṇavas, the most dear servants of Kṛṣṇa, sometimes dress like madmen. Just to benefit materialists like us, who are always attached to sense gratification, and just to dissipate our ignorance, these Vaiṣṇavas wander on the surface of the globe according to their desire.
