Temples are normally open throughout the day for individual worship.

The concluding ceremony of ‘arati' which all worshippers take part includes the lighting of five divas (lamps) by the priest who repeatedly circles the lamp in front of the central deity while worshippers sing a prayer accompanied by several musical instrument and a bell.

Afterwards, the lamp is brought amongst the worshippers who donate coin on the tray, then place their hands over the flame and touch their heads which gestures the accepting of the light of God and the comforting warmth of the divinity.

Thousands of temples dedicated to various deities, yet one common theme or thread that binds these is the celebration of life. Great importance has been attached to life force in Hindu Dharma. These temples dedicated to various deites reflect the secular thought in Hindu religion.
