Ringing of bells is an important practice in a Hindu Temple
One stroke of the bell indicates moksha or salvation. It is
performed by devotees whose sole prayer is self realization.
Two strokes is enjoyment. Thanksgiving for desires fulfilled
etc.
Three strokes are for achievement of materialistic desires.
A devotee strikes the bell three times when he prayers for fulfillment of
various desires.
During puja when lamp alone is lit one needs to stroke the
bell only a single time.
When incense is waved, lamp is lit and food is offered the
bell should be stroked two times.
It must be noted that today most devotees ring bells in
temple as an invitation to gods or to garner attention of the deity or announce
the presence of the devotee. Therefore, no rules are followed regarding stroking the temple bells.
