The following experience was to teach me what happens with people who are eager to enter heaven but are not of a type that can stay there.
Once while I was in a community in heaven, an angel appeared to me as a little child wearing a wreath of dazzling sky-blue flowers on its head and garlands of other colors circling its chest. From this sign I was able to recognize that I was in a particular community where charity existed. Then into the same community came some upstanding spirits who on entering suddenly became much more intelligent and started talking like angelic spirits.
Next to be admitted was a group of people who claimed to be innocent on their own merits. Their condition was represented to me by a baby spitting up milk. That is what such people are like.
Afterward came people who supposed that their own good thinking made them intelligent. Their condition was represented in their faces, which were angular but reasonably attractive. They appeared wearing pointed hats with a protruding spike. Still, their faces did not seem to be made of human flesh but looked like lifeless sculptures. This is the condition of those who believe that they can make themselves spiritual or acquire faith on their own.
Other spirits were allowed in who were unable to stay there. Overwhelmed with dismay and anxiety, they fled the place.
