Tying a thread on the wrist, a significant Hindu practice, symbolizes protection and a sacred bond. It traces back to ancient times, inspired by events involving deities like Lord Vishnu and Lord Krishna. The thread, known as Rakhi or Kalawa, symbolizes love, protection, and blessings, and is scientifically believed to stimulate a pulse point on the wrist, promoting well-being and balance. Typically tied on the right wrist, it signifies strength and righteousness.
