The ringing of the bell in the temple is symbolic as well as cleansing – the ringing of the bell creates a vibration that is very beneficial to some of the invisible chakras in the body. There are some temples where the ringing of the bell signifies something. As someone said, asking permission to enter the temple. By ringing the bell, the invisible beings in a temple are informed of our arrival, says another school of thought.
The resonance of the bell ring corresponds with Om, the Pranava. It is an auspicious sound that brings in beneficial vibrational changes. One of the more popular reasons ascribed by the elderly about the ringing of the bell, blowing of the conch, etc during religious festivals and functions is because these auspicious sound vibrations can minimize the other noises, some of which can be considered inauspicious. For example, the concept of “Getti Melam” in marriages at the precise moment of the tying of the thali appeals more to the concept of drowning out irrelevant or any other inauspicious noises. (for example, a curse by someone who is present at the wedding but who is not blessing the event!)
The ringing of the bell also is explained by slokas that say that the ringing of the bell drives out the evil forces from within one’s self, invoking divinity within.
