Mangala Snanam is a sacred ritual that is performed in many Indian weddings, especially in the South Indian states. It is a traditional ceremony that signifies the bride and groom's purity and spiritual cleansing before their union. Mangala Snanam is a privilege accorded only to the bride and groom, and it is performed separately, with the bride's family performing her Mangala Snanam in private, and the groom's family performing his in his ancestral home or temple.

The Mangala Snanam ritual consists of a ceremonial bath or shower with holy water, which is prepared by priests and blessed with mantras and chants. The ritual bath is usually taken early in the morning, before sunrise, and it is believed to cleanse the mind, body, and soul of the bride and groom. The holy water used in the Mangala Snanam is infused with medicinal herbs known for their therapeutic and healing properties. These herbs are believed to have a purifying effect and are said to possess the power to remove sins, negative energies, and disease-causing pathogens. The Mangala Snanam ritual concludes with the bride and groom wrapping themselves in fresh, new clothes that symbolize their new beginning as a married couple. The whole process is spiritual, soothing, and serene, and it sets the tone for a peaceful wedding ceremony.
