The vibrations of the ringing bell also produce the auspicious primordial sound ‘Om’, thus creating a connection between the deity and the mind. As we start the daily ritualistic worship (pooja), we ring the bell, chanting:

Aagamaarthamtu devaanaam

gamanaarthamtu rakshasaam

Kurve ghantaaravam tatra

devataahvaahna lakshanam

“I ring this bell indicating the invocation of divinity, So that virtuous and noble forces enter (my home and heart); And the demonic and evil forces From within and without, depart.”
