Rudra Devine Shank comes from the two Sanskrit words "Shum" which means something good and "Kham" meaning water. Hence the meaning of Shankar is conch holding the sacred water. It is also said word Shankara was been derived from Sankha-kara which means conch-blower (shankha means conch and Kara means blower). 1. When the Rudra Devine conch is blown with controlled breath, the primordial sound of "Om" emanates from it. This eternal sound is the origin of all Vedas. All knowledge enshrined in the Vedas is an elaboration of the omnipresent sublime sound of Om. It was this sound that was chanted by the Lord before manifesting the cosmos. It represents the creation and the Truth behind it. 2. The blowing of a conch shell enhances the positive psychological vibrations such as courage, determination, hope, optimism, willpower and bliss that can be felt by all people assembled and also by the blower. 3. As soon as the Shank is blown the frequencies of divine energy (Shakti) are emitted into the atmosphere due to sound generated These energy frequencies are seen in red colour. Along with these energy frequencies yellow circles of Chaitanya are also projected in the atmosphere. You can also see the pink particles of Bliss being emitted in the atmosphere. This increases the proportion of shakti (energy),
