Tao Te Ching

“Those who uncovered and touched this image of life were instantaneously destroyed and shall remain forever exposed to the play of the eternal waves. For the unutterable and the formless must be concealed.”

— Proclus Lycaeus Πρόκλος ὁ Διάδοχος 412 – 485 CE via Tobias Dantzig
"The most influential Ancient Greek philosopher you've never heard of"
