A ritual involving brother and sister, Bhai Phota is observed by Bengalies that is almost similar to the north Indian Bhai Dhooj. However, sometimes due to specific timings according to Hindu calendar, Bhai Phota may be celebrated on the third day of the month of Kartik, instead of the second. On Bhai Phota sisters apply tilak to brother's foreheads with mantras for long and happy life.
On the day of Bhai Phota, both brothers and sisters are decked in finery. Sisters apply a sandalwood paste ' tilak' or mask known as Phota on the forehead of their brothers, place some paddy grass known as "Dub" or "Dubya" on their heads and chant a verse for the siblings long life. Then they place a sweet in the brother's mouth. Of course, the ceremony is rounded off with a grand meal and the exchange of gifts. The merriment of Bhai Phota is increased amid the resounding of conch shells in every Bengali household.
