The aarti is always carried out facing the River Ganga. A lot of lamps are lit during the aarti. They are usually circled out by priests. It is always done clockwise. The aarti is always accompanied by different songs sung while praising the Ganga. It is believed that the lamps acquire the power of the deity.
After the aarti, devotees are supposed to cup their hands on the lamps over the flames and touch their foreheads. This is done in order to receive gratification and purification from the Goddess Ganga.
