The meaning of the bell inside temples

The bell is used in many religions, mostly in Christian and Hindu religions. In Christianity, the bell is rung with a different tone on different occasions. For example, for a wedding ceremony the

sound will be more a joyous one, while for a funeral, the sound will express sadness. Our moods reflect the modifications of our mental state. When we are in distress, we will not sing songs of joy. The reason for producing the different sounds is to remind us that our moods are nothing but a vibratory affair and can be changed by listening to specific kinds of music or sound. The chanting of songs accompanied by music in religion is meant to raise the consciousness to a higher level.
Such practice is one of the methods used in the science of Nad Yoga — union with God through the correct use of sound. Mantra chanting and recitation of AUM are among the other methods of this science.

The Indian mystic presents a deeper truth concealed behind the bell. In the Hindu temple, it is placed at the entrance of the sanctum sanatorium and the worshiper is supposed to sound the bell before entering therein. But we can ask what sense it makes to do this simple act of ringing the bell. Once, l heard a few people saying that this is done with the aim of awakening the Lord! At first, I thought it was a joke, then I realized that it is deeply mystical - it is related to the awakening of the Lord within. The sound of the bell symbolizes the vibration of the humming sound AUM that can lead the aspirant into the meditative state.

The real sanctum sanatorium is the deep recess of the heart wherein lies the meditative state. Therefore, by listening to that sound, the aspirant, is supposed to have a glimpse of that divine state and this would deepen his thirst for the inner and absolute truth. Why is the bell
rung before one goes inside? The message is direct: “Using that humming vibration as a means of awakening the inner Lord, step into the inner sanctuary." Of course, to obtain even a glimpse of the
meditative state by the mere sound of a bell is conditional upon certain factors. Firstly, the person who is ringing the bell must already be in quite a high level of mental evolution. Also, the bell must be made of the appropriate alloy to produce the exact humming sound that can usher the meditative mood. The aspirant yogi who has reached a certain level in his spiritual practice can, in fact, hear the humming sound even without having recourse to the sound of a bell or any other external factor.
