The soul in Jainism is neither a dimensionless point, as in some Indian systems, nor coextensive with the universe, as in Advaita. It has pradesha, spatial units, and it expands or contracts to exactly occupy whatever body it currently inhabits — an elephant's soul fills an elephant, an ant's an ant, and the same soul does both across successive lives. The standard image is a lamp in a room, whose light fills whatever container is placed over it. At liberation the soul retains slightly less than the shape of its final human body, which is why Siddhas are drawn as an empty human outline: the last form leaves a permanent impression. The doctrine matters practically because it grounds the moral equality of all life without erasing the difference between kinds — the soul is identical in nature everywhere, only differently housed and differently obscured. It also means there is no world-soul, no merging, and no ocean-and-drop metaphor. Liberated souls are infinitely many and remain distinct, all in the same place, forever, without interaction.
