Why are we preaching? Why, what was the necessity to come in the Western country? No. Krishna wants; Chaitanya Mahaprabhu wants. Therefore devotee goes from town to town, village to village. Prthivite ache yata nagaradi-grama (CB Antya-khanda 4.126). This is Vaishnava. He is thinking for everyone. Because it is a fact, without Krishna consciousness, everyone is suffering.That's a fact. So therefore preaching is so important -- to awaken them. Jiva jago, jiva jago, gauracand... This is Gauracanda, Chaitanya Mahaprabhu's mission, to awaken everyone from this material entanglement. That is preaching.
