Begging for Krishna

The vānaprastha or sannyāsī trying to become free from material attachment should avoid those who are working day and night for sense gratification, approaching them only to engage them in necessary acts of charity. Those who are preaching Kṛṣṇa consciousness all over the world are understood to be liberated souls, and therefore they constantly approach the materialistic living entities to engage them in the devotional service of Lord Kṛṣṇa. However, even such preachers should strictly avoid contact with the materialistic world when not actually necessary for advancing the mission of Kṛṣṇa consciousness. The injunction is that one should not deal unnecessarily with the materialistic world.....In the Western countries people are generally so dull that they cannot distinguish between a saintly beggar and an ordinary hobo or hippie. A saintly beggar is constantly engaged in authorized devotional service to the Supreme Lord and accepts only what he requires for his bare maintenance. The author of this book remembers entering the Kṛṣṇa consciousness society as an arrogant university student and being quickly humbled by the process of begging on the street on behalf of Kṛṣṇa. This process is not theoretical but actually purifies one's existence by forcing one to offer respect to all others.
