Science behind wearing Mangalsutra
As per Hindu Dharma, Mangalsutra is an ornament of a woman denoting her marital status. Each person makes a Mangalsutra for the bride as per his capacity. If it is not possible to make a Mangalsutra with a cord of gold or silver, they make it by stringing black beads in a thread. In the center of the Mangalsutra there are two cups. The cups should be round and there should be no design on its front. This structure is associated with the Energy of Knowledge.
