The festival in India that celebrates the bond between brothers and sisters is called Raksha Bandhan. This occasion includes rituals where sisters tie a protective thread, or rakhi, around their brothers' wrists, symbolizing their love and commitment to their safety. Brothers, in return, offer gifts and sweets, reflecting their appreciation for their sisters. The celebration emphasizes familial bonds and mutual respect, fostering unity among relatives while highlighting the cultural significance of these relationships within Indian society.
