A rakshasutra rakhi is a sacred thread worn for protection and divine blessings. The name itself comes from the Sanskrit words raksha, meaning "protection," and sutra, meaning "sacred thread". On Raksha Bandhan, sisters tie this thread on their brothers' wrists to symbolize their prayers for his well-being, while the brothers promise to protect them. The thread is not exclusive to siblings, as it can be tied to a priest, a guru, or other revered figures to seek blessings and ward off negative energy.
