Banaras is the city of spirituality. People come here from all over the world to perform pujas and other rituals. Red is a colour so sacred for Hindus and is irrespectively used in most of these rituals. If one walks along the ghats , the colour which stands out the most is the red, mainly from the sindhoor/kumkum . It almost looks like the red has embraced the entire city and ghats. Almost every single person ion the ghats during the aarti would have a red tilak on his/her forehead, a symbol of oneness, love and devotion despite all beliefs and differences.
