Mangala sutra
A Mangalsutra (Sanskrit: मङ्गलसूत्रम्, romanized: maṅgalasūtram), or Tali (ISO: tāḷi), is a necklace that the groom ties around the bride's neck in the Indian subcontinent, in a ceremony called Mangalya Dharanam (Sanskrit for 'wearing the auspicious') within a Hindu wedding. The necklace serves as a visual marker of status as a married Hindu woman.
The mangala sutra's origin dates back to the 4th century BCE as Mangalasutra in Lalita Sahasranama., even Purananuru a Sangam text mentions about a sacred marriage tail on women's neck. Further also finds a mention in the 6th century CE as a single yellow thread was tied around the bride for protection from other men and evil spirits. The tying of the mangala sutra is a social practice widespread in India, Sri Lanka, and Nepal.
