Anguttara Nikaya
The Buddhist text "Digha Nikaya" mentions Mahishmati as the capital of Avanti, while "Anguttara Nikaya" states that Ujjaini was Avanti's capital. The "Maha-Govinda Suttanta" also states that Mahishmati as the capital of Avanti, whose king was one Vessabhu. It is possible that the capital of Avanti was transferred from Ujjayani to Mahishmati temporarily.
