ON A HUMID September evening in an East Delhi park lined with Ashoka trees, a group of women gathers wearing traditional clothes in white with a pink border and in white shoes. One of the women blows a whistle, signalling them to fall into rows. Against drum beats, the hoisting of a saffron flag and constant commands, they move synchronously swinging long wooden sticks, their dupattas tucked around their waists, hair tied up. It is followed by a rhythmic drill of martial arts moves.
