May not heaven and hell be our present thought-forms which will give way to other thought-forms when we leave the body and go to the unknown?

The Catholic Answers

We do not go to the unknown, though we do go to the as yet unexperienced. Christ has revealed the essential elements of our future lot. Meantime heaven and hell are not our present thought-forms. Heaven is prepared independently of our thinking processes. Christ said definitely, “I go to prepare a place for you, that where I am you also may be.” Thus our own thoughts do not make heaven. Also Christ said, “Depart from me you cursed into the everlasting fire which was prepared for the devil and his angels.” Hell therefore is also independent of men’s thoughts.
