The animals that carried people here, waiting on the lowest deck.
Mounts and draught animals, set down at the outermost wall while those they brought climb further in.
They share the deck with the vimānas the gods arrived in — everything that was ridden, parked together.
Almost every retelling in English collapses this deck and the one above into 'animals and vehicles'. The texts do not: both decks hold animals, and the wall between them marks the difference between coming to hear and being brought.
