The lower level of the Cave 6 likely was the earliest excavation in the second stage of construction. This stage marked the Mahayana theme and Vakataka renaissance period of Ajanta reconstruction that started about four centuries after the earlier Hinayana theme construction. The upper storey was not envisioned in the beginning, it was added as an afterthought, likely around the time when the architects and artists abandoned further work on the geologically-flawed rock of Cave 5 immediately next to it. Both lower and upper Cave 6 show crude experimentation and construction errors. The cave work was most likely in progress between 460 and 470 CE, and it is the first that shows attendant Bodhisattvas. The upper cave construction probably began in 465, progressed swiftly, and much deeper into the rock than the lower level.
