Rakhi or raksha bandhan is celebrated among most Hindu Indians which symbolizes the strong bond of a brother and sister. The full moon day in the month of Shravana according to lunisolar Hindu calendar marks the celebration of Rakhi every years. It also signifies a magical protection of all sisters and the importance dates back to mythological era. When Laxmi tied a thread around Vishnu, in his dwarf incarnation, planned to slay the anti god bali. Also Sita tied Rakhi around Laxmana after her rescue, for the brotherly protection. Sisters tie a talisman or Rakhi on their brothers wrist and in return brothers give gifts, the rakhi is to protect their brothers against all evil.
