Call it just an odd vibe, or an intimation of the unusual. It’s just before noon, and devotees are just trickling in at the Nirgun Paduka, but there’s something in the air of this 500-year-old temple at Ganagapur, north Karnataka, that puts you on guard. As the crowd settles down in the enclosure in front of the sanctum sanctorum, waiting for the prayers to begin, some look restless, deep in thought. As the drums pick up the rhythm, the signs of agitation are unmistakable.
