"Somebody can be in the midst of chaos and death, but have the state of mind that is God’s, so they are "in" heaven, even if their environment doesn’t reflect that. But it also means that if you are in a pleasant environment, you can experience heaven manifest around you, thus Christ’s comments to the thief on the Cross: even this day, you shall be with me in my father’s house.
The idea of this King of Kings (king of fools, king of jews) telling this man, despite his pain and misery and soon death. The thief took these words as reassurance, that left him in a state of mind of Christ’s peace, despite the fact he was dying. So even prior to his death (not even talking about an afterlife here), he’s experiencing His Father’s house, because he believed (converted) to an ideal that was far beyond (“above”) the inconvenient (terminal) circumstances and environment …Happiness is a mental disease because it asks you to believe in that which is not possible, or present.” - my friend Cynthia’s friend Mark
