Aarti is a form of congregational worship, in which the devotees stand facing the image of a deity or a defied saint or, the personage (‘living idol’) of an exalted saint singing devotional songs in unison. Normally, the singing is accompanied by musical instruments such as bells, gongs and crymbals. The object of worship is devoutly decorated with posy garlands and, aromatic incence and musk are kept smouldering. While the devotees sing psalms, either an official or a devotee revolves clockwise, (usually) a fivefold oil lamp – consisting of five oil – traylets - round the object of adoration. Such a performance of aarti with a fivefold oil-lamp is called panchaarati.
