It is the run-up to Durga Puja and the roads are a mass of bamboo. Hammers can be heard in the narrow lanes as the pandal cages spring up, some faster than others. Evening brings snarls of traffic as commuters and sightseers jostle for space. At the end of it is a city filled with art installations – the craftsmanship of weeks of work suddenly on display for a few fleeting days before being dismantled with no record barring photographs and the name of the craftsmen, except in a few cases, anonymous. What a waste some people might say, while others sniff that whatever it is, it is not a religion and is, therefore, a waste of time.
