This piece is very simple to understand. It holds a magic that is called the angelic seed. Human are born from sperm and so are angels. It isn't the same type of sperm and there is no sex involve, but each angelic seed holds the ability to birth an angel, just a sperm holds DNA and can fertilize a woman's egg.
Angelic seeds required an energy source, which is usually God's energy when he is ready to birth more angels. However, this piece has been designed to work with human energy. When you wear this piece you will be able to fertilize the angelic seeds that have been implanted into this piece. These are energetic forms, so you obviously will not be able to see them.
However, when using the piece you will simply meditate with this piece. You will connect with it psychically. You will then name an angel and give it a power. Within 48-72 hours the angel will be birthed and will exist in the environment around you. You will be able to make contact with the angel, at which point you will be able to acquire the power that you have given it.
