Devotee (2): Swamiji? Why is it that in the mornings and the evenings we say bells before the Deity?
Prabhupāda: Bells?
Devotee (2): Prayers. Bells.
Prabhupāda: Oh, that is ceremonial. Yes. When you offer something to Kṛṣṇa in the temple, the system is that you offer with bell. That bell offering worship, even in Christian world there is bell, church bell. So that is system everywhere. Only in Muhammadan religion they don't allow any sound. Yes. But in Hindu religion or in other religion there is sound. Sound vibration. Our whole process is sound vibration. The Muhammadans, they offer silent prayer. That is also prescribed in devotional service.
