Yes. It exists on earth but so does heaven. If a person, lets say, worships a false god, a trinity, a mangod, the sun, the moon, the stars, a block of wood, or turns to a lifeless piece of bread made by human hands for spiritual life, then they die in the very day they do it and descend into the netherworld, Hades, hell, the realm of the dead.
In this sate of abject obliviousness where a persons only light in life is a lie, life is a curse, dying all the time, never finding peace in death, and REALITY, day and night, is like a raging eternal consuming fire that will never go out.
When a person diligently stands guard over the sanctity of their own mind life is a blessing a peaceful REALITY and they ascend into the realm of God, heaven, where they have an ecstatic experience of life day and night.
Wherever you stand purify your own mind and be refined and you will never know what it is do die.
If not you will never know what is like to live within the realm of my God.
