SB 11.18.29
budho balaka-vat kridet
kusalo jada-vac caret
vaded unmatta-vad vidvan
go-caryam naigamas caret
Translation:
Although most wise, the paramahamsa should enjoy life like a child, oblivious to honor and dishonor; although most expert, he should behave like a stunted, incompetent person; although most learned, he should speak like an insane person; and although a scholar learned in Vedic regulations, he should behave in an unrestricted manner.
Purport:
A paramahamsa-sannyasi, fearing that his mind may be deviated by the tremendous prestige that people sometimes offer to a perfectly self-realized person, conceals his position as described in this verse. A self-realized person does not try to please the mass of people, nor does he desire social prestige, since the mission of his life is to remain detached from the material world and to always please the Supreme Personality of Godhead. Although neglecting ordinary rules and regulations, a paramahamsa does not ever become sinful or immoral, but rather neglects ritualistic aspects of religious custom, such as dressing in a particular way, performing certain ceremonies or executing specific penances and austerities.
The pure devotees of the Lord who have dedicated their lives to propagating the Lord’s holy name must very expertly present Krsna consciousness in a way pleasing to the mass of people so that they will accept it. Those who are preaching should try to make Lord Sri Krsna popular without trying to advance their personal prestige in the name of missionary progress. A paramahamsa not engaged in distributing Krsna consciousness, however, should have no attachment whatsoever to public opinion.
