One should not go empty-handed to a temple merely for seeing the karpura-harati.
One should offer what one has brought to the priest, have darshan and return without showing his back to the Lord.
With folded hands, and reciting stotras, one should perform pradakshinas ranging between 3 and 21 times, preferably in odd numbers.
As for namaskarams, one should do it an odd number of times for Ishwara, ranging from 3 to 21, and for Devi four times.
After namaskara, one should do pradakshina and then return home.
All these rules have been prescribed only for our welfare and to preserve the sanctity of the temples.
It is up to us all to observe these rules, protect and nurture the sanctity of our temples, which have been the greatest heritage.
Jaya Jaya Shankara ! Hara Hara Shankara !!
