The New Christian Bible Study Project has imported a Spanish translation of Heaven and Hell. Here’s a link: El Cielo y El Infierno. It’s a 1911 translation that was done by Dr. Calleja. The team at swedenborg.es worked with the New Christian Bible Study people to provide this. More Spanish translations are on the way, and the NCBSP site also has Swedenborg’s works in other languages, too.
