River of Forgetfulness
Lethe

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 Story of Lethe

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.
