Around the middle of January, several thousand saffron-clad wandering minstrels or Bauls – the word means simply ‘mad’ or ‘possessed’ in Bengali – begin to gather at Kenduli, in the flat floodplains near Tagore’s old home of Shantiniketan. As they have done on this site for at least 500 years, the Bauls wander the huge campsite, greeting old friends, smoking ganja and exchanging gossip. Then, as the night draws in, they gather around their fires, and begin the singing and dancing that will carry on until dawn. You approach the festival through green wetlands, past bullocks ploughing the rich mud of the rice paddy. Reed-thatched or tin-topped Bengali cottages are surrounded by clumps of young green bamboo and groves of giant banyans, through which evening clouds of parakeets whirr and screech. As you near the Baul monastery of Tamalatala, which acts as the focus of the festival, the stream of pilgrims slowly thickens along the roadsides. Bengali villagers herding their goats and ducks along the high embankments give way to lines of lean, dark, wiry men with matted hair and straggling beards.
