Hiraeth.

Hiraeth is a Welsh word which describes the longing and homesickness for a place that doesn't exist as far as this world is concerned. This is a good definition of what this word means as a concept, "A spiritual longing for a home which maybe never was. Nostalgia for ancient place to which we cannot return. It is the echo of the lost places of out soul's past and our grief for them. It is in the wind, and the rocks, and the waves. It is nowhere and it is everywhere." The last statement this home being everywhere and nowhere is a good description of how the singularity is stretched out so that it can no longer be perceived. 

There are a certain number of people in this world who have the faintest memory that they used to be somewhere else, but they can't put their finger on it. Even though this memory is so faint it continually bugs them like a splinter in the mind constantly reminding them they don't belong in this desert of the real. Such people are more likely to pursue occultism or mysticism to start trying to remember what they had left behind.

The Prodigal Son in the Bible is a very good story about this state of being. The Exegesis of the Soul is the Gnostic version of the Prodigal Son story and the salvation is about being restored to the place the soul had come from. The Gospel of Thomas tells readers to "Become passers by" meaning only consider this world to be a brief stay and nothing more. Another passage in the Gospel of Thomas makes this statement, "Whoever has come to understand the world has found only a corpse, and whoever has found a corpse is superior to the world." That was perhaps the reason why the occultist and mystic is subconsciously turned off from this world, because it is death wearing make up.

The Bible itself makes it clear where that higher world is in Luke 17:20, "The kingdom of God cometh not with observation: Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you." Only within in the midst of reality is the other place accessed. The Egyptian proverbs mentioned on this website have similar statements, "The kingdom of heaven is within you; and whosoever shall know himself shall find it." Also this statement from the same website, "Know the world in yourself. Never look for yourself in the world, for this would be to project your illusion." This is really on the same level of understanding as each other.
