Raksha Bandhan

Raksha Bandhan (Marathi: रक्षा बंधन Hindi: रक्षा बन्धन) is also called Rakhi Purnima or simply Rakhi or "Rakhri", in many parts of India. The same festival is celebrated as Janai Purnima (जनै पूर्णिमा) in Nepal.
The festival is a Hindu festival and is also a secular festival which celebrates the love and duty between brothers and sisters. The festival is also popularly used to celebrate any brother-sister relationship between men and women who are relatives or biologically unrelated.
The festival is also observed by Jains as a religious festival, as on Raksha Bandhan, Jain priests give threads to devotees.
The festival is also celebrated by many communities as a secular festival. This secular aspect is observed among all people, irrespective of their religion, in West Bengal and Punjab. Various fairs are held in Punjab to mark the occasion.
On Raksha Bandhan, sisters tie a rakhi (sacred thread) 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 Nepali calendar.
Raksha Bandhan is primarily observed in northern and western India, Mauritius and major parts of Nepal. It is also celebrated by Hindus in parts of Pakistan, and by some non-resident Indians and non-resident Nepalis around the world.
Raksha Bandhan as a religious festival focuses on performing the aarti and saying prayers prior to tying the rakhi. The prayers draw inspiration from the Hindu scriptures. The other religious feature is the application of the tilak on the forehead of the person wearing the rakhi.
Raksha Bandhan in Sanskrit literally means "the tie or knot of protection". The word Raksha means protection, whilst Bandhan is the verb to tie. It is an ancient Hindu festival that ritually celebrates the love and duty between brothers and their sisters. The sister performs a Rakhi ceremony, then prays to express her love and her wish for the well being of her brother; in return, the brother ritually pledges to protect and take care of his sister under all circumstances. It is one of the several occasions in which family ties are affirmed in India.
The festival is also an occasion to celebrate brother-sister like family ties between cousins or distant family members, sometimes between biologically unrelated men and women. To many, the festival transcends biological family, brings together men and women across religions, diverse ethnic groups and ritually emphasizes harmony and love. It is observed in the Hindu calendar month of Śrāvaṇa, and typically falls in August every year.
The festival is marked by the several rituals, which vary regionally within India. Typical rituals include:

Prepare for Raksha Bandhan

Days or weeks before Raksha Bandhan, women shop for Rakhi, the ceremonial thread to tie around her brother's (or brother-like friend's) wrist. Some women make their own Rakhi. A Rakhi may be a simple thread, woven and colorful; or a Rakhi may be intricate with amulets and decoration on top of it. Sometimes, a Rakhi may be a fancy wrist watch or men's wrist accessory in the form of bracelet or jewelry. Rakhi in the form of a colorful woven thread is most common. Typically the brother(s) too shop for gifts for the sister, ahead of Raksha Bandhan. The gift from the brother can be a simple thoughtful token of love, and may be more elaborate.

On the morning of Raksha Bandhan the brothers and sisters get together, often in nice dress in the presence of surviving parents, grandparents and other family members. If the sister and brother are geographically separated, the sister may mail the Rakhi ahead of the Raksha Bandhan day, along with a greeting card or letter wishing her brother well. The ritual typically begins in front of a lighted lamp (diya) or candle, which signifies fire deity. The sister and brother face each other. The sister ties the Rakhi on her brother's wrist

May all negativity and fears, spirits malignant and unfriendly, flee thee;
May Rishikesa keep you safe in the sky; and Mahidhara, upon earth.
