According to the Skandpuran, the ringing of temple bells absolves man from sins committed over hundred births. Let us now see how the energy is emitted from the bell and what exactly happens with the help of a subtle drawing.
The dome shaped body of the bell and the clapper when strike with each other create circles of chaitanya which are projected in the atmosphere. The sound generated simultaneously also emits frequencies of chaitanya predominant in Akash tattva (absolute ether element). We can see them in yellow colour. The stroke of clapper emits red coloured divine energy rays. The particles of divine energy which spread in the atmosphere and are of red colour are also seen here. The divine energy and chaitanya generated by the sound of bell drives away the negative energies.
Kurve ghantaaravam tatra
Means: 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.
