Arcana Coelestia #1772
1772. In the Lord's Divine mercy I too have been allowed in a similar way to see the Word of the Lord in its beauty in the internal sense. I have seen it many times, not when individual expressions are being explained as to their internal sense, but when every single thing is presented in a single sequence of thought. This may be called seeing a heavenly paradise by means of an earthly one.
