“Devotees are infused with bhakti-sakti, and Krishna consciousness comes out through every pore in their body. Just as someone can get a person’s disease by eating the remnants of his or her food, because devotees are infected by Krishna consciousness, by coming in touch with them—through the dust of their feet, the water that has washed their feet, or the remnants of their food—one can get that infection. And we want that infection.

‘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.’ (Cc Antya 16.60)
“It is by the association of devotees that one comes to Krishna consciousness. And even after developing love for Krishna, the association of devotees is still most essential.

‘The root cause of devotional service to Lord Krsna is association with advanced devotees. Even when one’s dormant love for Krsna awakens, association with devotees is still most essential.’ (Cc Madhya 22.84)”
