The Lighthouse seems to me a more enlighted way of seeing The Tower that usually as a bad reputation. I believe that all Arcana have a bright side and a shadow. The bright side of this card is revelation and rest on solid ground.
Revelations might surprise us in a terrible way but they also may show good and powerful things. This image points to that direction. It's a beutiful painting from the artist Ilídio Salteiro. I am very grateful for this contribuition for the Never Ending Tarot.
