Raksha Bandhan (also celebrated as Rakhi) is a festival which celebrates the bond of affection between brothers and sisters.Raksha Bandhan is celebrated on the full moon day of the month of Shraavan (as per Hindu calendar), i.e. in the months of July and August. The central ceremony involves the tying of a rakhi (sacred thread) by a sister on her brother’s wrist. The sister applies Tikka on her brothers forehead and performs aarti. This symbolizes the sister’s love and prayers for her brother’s well-being.  The brother in return offers a gift to his sister and vows to look after her as she presents sweets to her brother. The brother and sister traditionally feed one another sweets.Girls and women often tie  rakhi to their male cousins as well (referred to as cousin-brothers) in several communities. Unrelated boys and men who are considered to be brothers (munh-bola bhai or adopted brothers) can also be tied rakhis, provided they commit to a lifelong obligation to provide protection to the woman or girl.

Legends of Rakshabandhan:

• Yama and Yamuna:
  Yamuna was the sister of Lord Yama, the God of death. On every “Shravan Purnima”, Yamuna used to tie a sacred thread (Rakhi) to Lord Yama. Since then, it has become a tradition for sisters to tie Rakhi to their brothers on this day. In return, the brothers bestow blessings on their sisters and promise to protect them all the problems and difficulties that they might ever face.
• King Bali and Goddess Laxmi:
  According to the mythology, Raja Bali was such a great devotee of Lord Vishnu that Lord Indra felt insecure. Indra worshipped Vishnu and asked the Lord to help him save his throne. Vishnu accepted Indra’s prayer and overthrew Bali. Later, Vishnu gave Bali the boon of immortality and also promised to take care of his kingdom. To keep his promise, Vishnu left his residence, ‘Vaikunthdham’, and went to safeguard Bali’s kingdom. Soon, Goddess Laxmi, wife of Lord Vishnu, went to Raja Bali, as a poor Brahmin lady, and requested him for shelter. She regarded Bali as her brother and tied a Rakhi on to his wrist, on the ‘Shravan Poornima’ day. When Bali wished to give her some present, she told him her true identity and the reason for her arrival. She also asked Bali to send Lord Vishnu back to Vaikunthdham. Raja Bali immediately requested Lord Vishnu and Goddess Laxmi to return.
• King Porus and Alexander’s Wife:
  The ancient history of India tells us that when Alexander the great came to India, to make it a part of his kingdom, he was resisted by the brave King Porus. The bravery of Porus led the Alexander’s wife to doubt the safety of her husband. Soon, she sent Porus a rakhi and became his sister. This is the reason why Porus never harmed Alexander.
• Lord Krishna and Draupathi:
  In order to protect the good people, Lord Krishna killed the evil King Shishupal. Krishna was hurt during the war and left with bleeding finger. Seeing this, Draupathi had torn a strip of cloth from her sari and tied around his wrist to stop the bleeding. Lord Krishna, realizing her affections and concern about him, declared himself bounded by her sisterly love. He promised her to repay this debt whenever she need in future. Many years later, when the pandavas lost Draupathi in the game of dice and Kauravas were removing her saari, Krishna helped her divinely elongating the saari so that they could not remove it.
