The tradition of wearing sindoor (vermillion) by married women has been explained in Indian mythology. According to religious scriptures, red is the color of power and sindoor represents the female energy of Sati and Parvati. Sati is considered an ideal Hindu wife because she gave her life for her husband's honor.
In Indian weddings, the Mangala Sutra is tied around the bride’s neck instead of exchanging rings. The mangala sutra is a cord with two gold pendants and is tied in three knots by the groom to symbolize the bonding of the two souls for 100 years. This necklace lets others know that the bride is married.
