St. Paul describes in 1 Corinthians 12:3-4 being taken up into Paradise. He says it is not proper for him to tell what he saw there. St. Ephrem the Syrian (4TH C) in his HYMNS OF PARADISE (p 110) offers poetic ideas about paradise:
“Paradise raised me up as I perceived it,
it enriched me as I meditated upon it;
I forgot my poor estate,
for it had made me drunk with its fragrance.
I became as though no longer my old self,
for it renewed me with all its varied nature.
I swam around in its magnificent waves;
and in the place that, burning like a furnace,
had made Adam naked,
I became so inebriated that I forgot all my sins there.”
