"Close inspection of the pillars and pilasters of the east corridor revealed, in several places, that the buds carved near the lotus medallion are irregular in shape and size as well as in their execution. These disconformities in what should have been uniform styles of execution suggest that the vyala were meant to be integral part of the decorative motif of the pillars and pilasters and that subsequently these depictions were removed and replaced with series of buds at the time of their reuse in the existing structure."
