same level of other caves was poor and they had a better chance of a major vihara at an upper location. Another likely possibility is that the planners wanted to carve into the rock another large cistern to the left courtside for more residents, mirroring the right, a plan implied by the height of the forward cells on the left side. The Archaeological Survey of India dates it to the 6th century CE. Spink, in contrast, dates this cave's inauguration a century earlier, to about 463 CE, based on construction style and other inscriptions. Cave 4 shows evidence of a dramatic collapse of its ceiling in the central hall, likely in the 6th century, something caused by the vastness of the cave and geological flaws in the rock. Later, the artists attempted to overcome this geological flaw by raising the height of the ceiling through deeper excavation of the embedded basalt lava. The cave has a squarish plan, houses a colossal image of the Buddha in preaching pose flanked by bodhisattvas and celestial nymphs hovering above. It consists, of a verandah, a hypostylar hall, sanctum with an antechamber and a series of unfinished cells. This monastery is the largest among the Ajanta caves and it measures nearly (35m × 28m). The door frame is exquisitely sculpted flanking to the right is carved Bodhisattva as reliever of Eight Great Perils. The rear wall of the verandah contains the panel of litany of Avalokiteśvara. The cave's ceiling collapse likely affected its overall plan, caused it being left incomplete. Only the Buddha's statue and the major sculptures were completed, and except for what the sponsor considered most important elements all other elements inside the cave were never painted. Cave 5 Cave 5, an unfinished excavation, was planned as a monastery (10.32 × 16.8 m). Cave 5 is devoid of sculpture and architectural elements except the door frame. The ornate carvings on the frame has female figures with mythical makara creatures found in ancient and medieval-era Indian arts. The cave's construction was likely initiated about 465 CE but abandoned because the rock has geological flaws. The construction was resumed in 475 CE after Asmakas restarted work at the Ajanta caves, but abandoned again as the artists and sponsor redesigned and focussed on an expanded Cave 6 that abuts Cave 5. Cave 6 Cave 6 is two-storey monastery (16.85 × 18.07 m). It consists of
