Please Simon (N) is asking about the Project and wondering if he is on the right lines.

The diamond is a symbol of purity. (N) is right about the Kingdoms but We are looking at the symbolism. The are plants, animals, humans, Stars and Galaxies that exude that purity.

Some more words to add to describe the symbolism are: Love and Gentleness. So a diamond is a symbol of Love and Gentleness.

That is why a diamond is chosen to wear in a ring to symbolise the Love in a marriage.
So there are certain birds, fish, animals, gemstones, and humans that exist as an embodiment of purity.

With the Diamond Light Project We are joining together the Pure Souls on Earth with the 33 points in Galaxies, so that the Purity Flows.
