Why do we celebrate Rakhi (Raksha Bandhan) in India? What is the significance?

“Raksha Bandhan”, the sacred bond of protection between a brother and a sister. In India, the full moon night that falls in the month of “Shravan” is celebrated as “Rakhi Purnima”. Rakhi is symbolized by a thread that the sister ties around her brother’s wrist. She wishes for his good health and well being in general. The brother promises to provide her protection from evil forces.
