Thirukkural-On Virtue-Impermanence Of The World-Kural 340

The soul, is, as it were, a passing guest in the body,Without a permanent abode of its own.

Indeed, the soul is to be considered a homeless wanderer. It lingers for a brief interlude in the body even as a temporary guest, who quits the place as early as possible. The soul being immortal and the body subject to decay, is the idea that has given rise to this kural.
