The most important activity of bhakti-yoga (Krishna Consciousness) in the modern age is Kirtan, or chanting the holy names of God. Kirtan is group activity, where people gather together for ecstatic congregational dancing and chanting of the Hare Krishna Mahamantra, accompanied by rhythmic instruments. During kirtan devotees chant and dance in glorification of the Lord.
Aarti is a traditional ceremony in which various articles are offered to the Lord’s Deity form. According to the Vedic scriptures the deity is the worshipful form of God, locally manifest so that the devotees can personally render some service to Him. The priest begins by blowing a conch-shell. The following items are offered: incense, ghee wick lamp, water, cloth, flowers, a chamara (whisk), and, in the summer, a peacock fan. These items represent the material elements in pure form. Aarti reminds us to offer everything in service to Lord Krishna.
