Yama and the Yamuna According to another legend, Raksha Bandhan was a ritual followed by Lord Yama (the Lord of Death) and his sister Yamuna, (the river in northern India). Yamuna tied rakhi to Yama and bestowed immortality. Yama was so moved by the serenity of the occasion that he declared that whoever gets a rakhi tied from his sister and promised her protection, will become immortal.
