Ariyalur , Sunlight falls on the lingam at the Selandaranayaki Amman Udanurai Pasupathiswara Temple, built over a thousand years ago in the village of Karaikurichi next to Palur.
Every year on the 10th day of the month of Chittirai, the sun shines on the lingam for one or two consecutive days.
This ray of light shone directly on the lingam and shone like gold melting gold. It continues for 10 minutes. Devotees are not allowed to see this.
