In Hindu culture bells plays a very important role. From temples to altars at home they are almost always used in rituals. 1. Traditionally the bell was supposed to be rung before starting worship with an intention that the divine enters you and all demonic forces within your soul depart and so do the ones outside it. 2. It is crafted with several metals and alloys and quantities of these metals are mixed with accurate scientific calculations. As a result when you ring the bell complete harmony is created between the left and right lobes of the brain bringing you to a state of supreme calm.3. The echo touches the seven chakras of the body taking a minute on each which completely relaxes your body. 4. The aura of uttermost calm created by the sound allows for the power of concentration in the brain to increase immensely and become strong. 5. The environment created puts you in a state of trance that takes calmness and worship to another level.6. It prepares you for the prayer you are going to start wakes you up and puts you in a state of awareness about prayer so you can get lost in the mantras for a moment and absorb maximum spiritual gain. 7. A type of temple bell is also designed to produce the sound 'Om' a sound that is believed to have the same frequency as the frequency of the earth's rotation around its axis.
