Lethe

place
Λήθη
River of Forgetfulness

Lethe was the River of Forgetfulness in the underworld — the dead drank from it to erase all memory of their mortal lives before reincarnation.

The Myth

Souls destined for reincarnation were required to drink from Lethe, forgetting everything they had known and experienced. In Plato's Republic, souls choose their next life and then drink from Lethe before being reborn. The Orphic initiates were taught to avoid Lethe and drink instead from the spring of Mnemosyne (Memory), preserving their awareness through the cycle of rebirth. The concept resonated powerfully — forgetting as a prerequisite for beginning again.

Fun Fact

The Greek word for "truth" — aletheia — literally means "un-forgetting" (a-lethe), implying truth is what survives Lethe's waters.
