It is hardly possible to find a single Bhakta (devotee) of Krishna among 100,000 liberated persons.
Devotees whose tongues are decorated always with prayers to Lord Krishna are always given respect even by the great saintly persons and sages, and such devotees are actually worshipable by the demigods.
When the devotees of Lord Krishna dance, their steps crush the inauspiciousness of the earth, their glances destroy the inauspiciousness of the ten directions and their raised arms push away the inauspiciousness of the demigods' planets.
The dust of the feet of a devotee, the water that has washed the feet of a devotee and the remnants of food left by a devotee are three very powerful substances.
The root cause of devotional service to Lord Krishna is association with advanced devotees. Even when one's dormant love for Krishna awakens, association with devotees is still most essential.
As far as the great devotees of the Lord are concerned, they can purify a degraded soul just by being them and what to speak of the benefits of their association.
