A fertility scrine???

Hampi, 14-12-1994. Almost at the top of Archyutaraya Temple is the entrance to a small cave dedicated to Lord Shiva. Through a semi-dark tunnel of about a km. in length which is sometimes broad and huge and at other times small and pitch dark, we got to a small chamber with a small lingam. I imagine the place to be a small temple dedicated to fertility. I imagine the childless women in the village and from far away to come up there and make sacrifice and offerings in the hope to get pregnant with a son. I imagine the oldest and childless spinster in the village living up there taking care of the scrine. I imagine this place to be stricktly OFF LIMITS to all males, females only!!!....There were actually quite a number of local women up there shyly looking away from us and there WAS an old woman at the place who looked quite upset at us being there..........
