In India the system is that people go to see the Jagannatha Deity. The Deity is not very beautiful from the artistic point of view, but still people attend by the thousands. That sentiment is required. Similarly with our kirtana we are only using drums and karatalas, but people come to the point of ecstasy. It is not the ornamentation, it is the ecstasy. This ecstasy is awakened by sravanam kirtanam by devotees.
