Kirtana means both lecturing and chanting with music. The chanting with music is specially attractive for the mass of people, but talking from philosophical point of view on Krishna Consciousness is also chanting. The whole Srimad-Bhagavatam is full of philosophical discussions and we are prepared to present our Krishna Consciousness movement both ways, whichever is suitable in special circumstances.
