Raksha Bandhan is celebrated in some parts of India as a festival to honor the sea god Varuna. However, at most places, it celebrates the love of a brother for his sister.
On this day, sisters tie rakhi on the wrists of their brothers to protect them against evil influences.
Through the passage of time festivals are undergoing modifications. Raksha Bandhan is also known as Rakhi. Rakhi has become a sacred festival for sisters and brothers. Sisters tie them to brothers. Priests tie them to people of his congregation. During the middle ages, if a woman tied a Rakhi on the hand of any man, then it became imperative for him, as his religious duty of the highest order, to protect that woman. That man would put his life at stake to protect the honor of that woman.
In those days, many Rajputs sacrificed their lives to protect their spiritual sisters. Humayun received a Rakhi from the queen Karmavati of Chittor and for that, Humayun carried out his sacred brotherly duty and protected her by opposing his own soldiers.
