Kirtan is Sanskrit for “chant” or “glorify”—mainly, to glorify God and chant His names. God has many names—in many languages—which are all spiritual. “Spiritual” means God and His names are the same, so saying “Krishna” means Krishna is present. For a devotee endeavoring to build a spiritual connection with the Supreme Lord, Kirtan is an important component. With a harmonium, even prayers sound melodious. The connection builds up sooner when one chants and sings the prayers and Lord's glories with musical instruments, especially harmoniums.
