"It is dated Samvat 1241 or A.D. 1184, in the time of Jaychchandra of Kanauj, whose praises it records for erecting a Vaishnava temple, from whence this stone was originally brought and appropriated by Aurangzeb in building his masjid known as Treta-ki-Thakur. The original slab was discovered in the ruins of this Masjid."
