Palace scene

East Gate of Stupa #1, Sanchi

From the right post. The fortunate denizens relax "at ease" behind a colonnade, and view the passing scene from an upper balcony. Since many scenes on the gateways depict events in the life of the Buddha, this might represent Prince Siddhartha's palace in Kapilavastu, where he lived before setting out on his quest for enlightenment.
