Most of these porticoes were of Roman period - the finest of them were erected, as we learn from inscriptions, by a lady named Epigone: one, which faced south, had a double colonnade, and was called the Bai-rn: close to it was a large exedra.
It was always the prayer that the soul (bai) should be able to revisit the corpse (khat), and some inscriptions show an expectation of the body itself being revivified, "the mouth speaking," "the legs walking," and everything conforming with its previous terrestrial life.
At the same time the ko (" life," "activity," and almost "ghost,") which clung to the neighbourhood of the tomb and enjoyed the ghosts of offerings in ghostly fashion, had some of the independent enterprise which the bai possessed in abundance.
His rule was weak; the state was distracted by interminable palace intrigues and military mutinies, and affairs went from bad to worse when, in 1843, Jankoji Rao, who left no heir, was succeeded by another boy, adopted by his widow, Tara Bai, under the name of Jayaji Rao Sindhia.
Another but less probable explanation derives the name from a combination of the old high German word uudra, meaning league, and bai, a Gothic word for both.
