The profound meaning of Sindoor Khela is in favor of the longevity of spouses. Women attending the rite pray for the peace and prosperity of their families. Before immersion, married women apply the sindoor on the forehead of their goddess.
Folk tradition later extended the use of the sindoor function in a profane sense. It gets used by Indian women to report their status as brides in the North of the country. In Aryan society, it was customary for the groom, to draw a sign with his own blood on the forehead of his future wife. It was a symbol of marital commitment. Today, at the Hindu wedding ceremony, the groom puts sindoor on to symbolize conjugal life.
The custom has survived, to the point that a widowed woman has to stop bearing the mark. The probable tribal tradition was later absorbed by religion. It symbolizes the ancient practice of offering blood sacrifices to please the Gods. Over time, communities have put an end to these sacrifices but the red color has remained.
Thus, the application of the sindoor is also a change of married wife status. So the sindoor also plays the role of a silent symbol of communication. If there is a mourning in the family, the women do not wear the sindoor. During menstruation, some women refrain from wearing sindoor.
In the past, women used this little sign on her husband's forehead. It was to bring him luck on the battlefield or to welcome him home. In modern times it gets used to welcome guests. Bindi and Kumkum bring with it a wealth of meaning and linked to a very ancient tradition.
