Raksha Bandhan

Raksha Bandhan, (the bond of protection) or Rakhi is a Hindu festival primarily observed in India, Mauritius and Nepal(Madheshis only), which celebrates the relationship between brothers (shaurya), cousins and sisters (shreya). It is also called Rakhi Purnima in most of India. It is also celebrated in some parts of Pakistan. The festival is observed by Hindus, Jains, and some Sikhs.
In fact, the popular practice of Raksha Bandhan has its historical associations also. The Rajput queens practised the custom of sending rakhi threads to neighbouring rulers as token of brotherhood. The central ceremony involves the tying of a rakhi (sacred thread) by a sister on her brother's wrist. This symbolizes the sister's love and prayers for her brother's well-being, and the brother's lifelong vow to protect her. The festival falls on the full moon day (Shravan Poornima) of the Shravan month of the Hindu lunisolar calendar. One Islamic Scholar believes that Raksha Bandhan grew in popularity after Rani Karnavati, the widowed queen of Chittor, sent a rakhi to the Mughal emperor Humayun when she required his help.

Interesting facts about Rakhi

Yama, the lord of death, was blessed with eternity as his sister Yamuna tied up a Rakhi thread on his wrist. Since that time the festival of Raksha Bandhan is associated with tying of Rakhi thread.
Lord Krishna was left with a bleeding finger, after Shishupal's death. To stop bleeding, Draupadi, the wife of the Pandavas, tore a strip of silk off her sari and tied it around Krishna's wrist. Touched by her concern, Krishna declared that he would protect her and promised to repay the debt manifold, and spent the next 25 years of his life doing just that.

Queen Karmavati of Chittor had sent a Rakhi to Humayun to protect her from Bahadur Shah. Humayun, then engaged in an expedition against Bengal, turned back to carry out his sacred brotherly duty and tried to protect her but was too late. Chittor had already fallen and the Rani had immolated herself in the Rajput custom of Jauhar.

Rabindranath Tagore, the Nobel laureate poet used the occasion of the Raksha Bandhan as a community festival and gave a call to tie a rakhi amongst all Hindus and Muslims so as to maintain peace and harmony between them and spread the nationalist spirit among people from different ethnic backgrounds.
