What is the central ritual performed by sisters for their brothers on Bhai Dooj?

On Bhai Dooj, the central ritual involves a sister applying a ceremonial tika (vermilion mark) on her brother’s forehead, praying for his long life, happiness, and prosperity. The sister also performs an aarti, often placing her brother on a special seat, and offers him sweets. In return, brothers give gifts to their sisters, expressing love and appreciation. This ritual symbolizes protection and blessings from sisters, while brothers pledge to care for their sisters. It is similar to Raksha Bandhan but without tying a rakhi. The emphasis is on family bonding, mutual respect, and the cultural importance of sibling relationships.
