Cancer 12. A diamond light enough to float.
The inner traveler Tinarus speaks of diamonds so light that they bear only the vaguest connection to gravity. They are found on a certain hidden island that wards off explorers, for the island resists all thought and perception, and so is never seen by passing travelers.
Tinarus says that beings from the star called Shenkar are the ones who grew this island to be as a womb to hold these miraculous gems, which the island is devoted to both concealing and protecting. It is said that the purpose of these gems is to draw into themselves and digest a part of the heaviness of our world, so that we may be, at least to an extent, unburdened of our darkness.
Occasionally by the action of an earthquake or volcano or the undermining of a cliff by the perpetual pounding of surf one of these diamonds is dislodged and floats away, wandering the ocean until it washes up far from its home on one of the coasts we know.
Tinarus says that even when a diamond of this island enters in this manner our world that it is never found, for it becomes invisible, and is only to be seen occasionally in dreams, where it finds a new home in which to work its magic, but is hardly ever remembered.
