Why do we blow the conch? When the conch is blown, the primordial sound of Om emanates. Om is an auspicious sound that was chanted by the Lord before creating the world. It represents the world and the Truth behind it. As the story goes, the demon Shankhaasura defeated devas, the Vedas and went to the bottom of the ocean. The devas appealed to Lord Vishnu for help. He incarnated as Matsya Avataara - the "fish incarnation" and killed Shankhaasura. The Lord blew the conch-shaped bone of his ear and head. TheOm sound emanated, from which emerged the Vedas. All knowledge enshrined in the Vedas is an elaboration of Om. The conch therefore is known as shankha after Shankaasua. The conch blown by the Lord is called Paanchajanya. He carries it at all times in one of His four hands. It represents dharma or righteousness that is one of the four goals (purushaarthas) of life. The sound of the conch is thus also the victory call of good over evil. Another well-known purpose of blowing the conch and the instruments, known traditionally to produce auspicious sounds is to drown or mask negative comments or noises that may disturb or upset the atmosphere or the minds of worshippers. Ancient India lived in her villages. Each village was presided over by a primary temple and several small ones. During the aarati performed after all-important poojas and on sacred occasions, the conch used to be blown. Since villages were generally small, the sound of the conch would be heard all over the village. People who could not make it to the temple were reminded to stop whatever they were doing, at least for a few seconds, and mentally bow to the Lord. The conch sound served to briefly elevate people's minds to a prayerful attitude even in the middle of their busy daily routine. The conch is placed at the altar in temples and homes next to the Lord as a symbol of Naada Brahma (Truth), the Vedas, Om, dharma, victory and auspiciousness. It is often used to offer devotees thirtha (sanctified water) to raise their minds to the highest Truth. It is worshipped with the following verse. Twam puraa saagarot pannaha Vishnunaa vidhrutahakare Devaischa poojitha sarvahi Panchjanya namostu te Salutations to Panchajanya the conch born of the ocean Held in the hand of Lord Vishnu and worshipped by all devaas

Om is one of the most chanted sound symbols in India. It has a profound effect on the body and mind of the one who chants and also on the surroundings. Most mantras and vedic prayers start with Om.

All auspicious actions begin with Om. It is even used as a greeting - Om, Hari Om etc. It is repeated as a mantra or meditated upon. Its form is worshipped, contemplated upon or used as an auspicious sign.

Om is the universal name of the Lord. It is made up of the letters A (phonetically as in "around"), U (phonetically as in "put") and M (phonetically as in "mum"). The sound emerging from the vocal chords starts from the base of the throat as "A". With the coming together of the lips, "U" is formed and when the lips are closed, all sounds end in "M".

The three letters symbolize the three states (waking, dream and deep sleep), the three deities (Brahma, Vishnu and Shiva), the three Vedas (Rig, Yajur and Sama) the three worlds (Bhuh, Bhuvah, Suvah) etc. The Lord is all these and beyond.

The formless, attributeless Lord (Brahman) is represented by the silence between two Om Chants. Om is also called pranava that means, "that (symbol or sound) by which the Lord is praised". The entire essence of the Vedas is enshrined in the word Om. It is said that the Lord started creating the world after chanting Om and atha. Hence its sound is considered to create an auspicious beginning for any task that we undertake. The Om chant should have the resounding sound of a bell (aaooommm).

Om is written in different ways in different places. The most common form symbolizes Lord Ganesha’s. The upper curve is the head; the lower large one, the stomach; the side one, the trunk; and the semi-circular mark with the dot, the (modaka) in Lord Ganesha's hand. Thus Om symbolizes everything - the means and the goal of life, the world and the Truth behind it, the material and the Sacred, all form and the Formless.
