Raksha Bandhan
Rakṣhābandhan is a Hindu festival to epitomize and celebrate the brother-sister relationship. It falls on the Śhrāvan Pūrṇimā (full moon day of Śhrāvana month) which comes generally in the month of August . On this occasion, sisters tie a holy thread (Rākhi) on the hands of their brothers’ wrists signifying ‘a bond of protection’ expressing their affection. In return, brothers offer gifts to their sisters and vows to take care of them. This occasion calls for pure family celebration creating a feeling of oneness in the family.
It is not necessary that the Rākhi should be tied to a blood brother - any male can be "adopted" as a brother by tying a Rākhi on the person. The Rākhi may be bound on other special occasions (not necessarily only among brothers and sisters), as was done during the Indian Independence Movement, Partition of Bengal, etc. The Indian independence movement was a series of steps taken in the Indian subcontinent for independence from British colonial rule, beginning with the Rebellion of 1857.
