A Thali thread (or Thali Kayiru) is a sacred yellow string used in traditional South Indian Hindu weddings to hold the bride's gold pendant, called the Thali.
It acts as the ultimate symbol of marriage, unity, protection, and lifelong commitment between a husband and wife.
It consists of multiple strands of cotton thread dyed bright yellow using turmeric water. Turmeric represents purity, fertility, and auspiciousness.
The central gold pendant (Thirumangalyam) slides onto this thread. The pendant's design varies based on the family's specific caste, culture, and regional traditions.
The groom ties the thread with exactly three knots. These knots represent his promise to honor and protect his wife through his Mind (Manasa), Speech (Vacha), and Actions (Karmena).
