And all the books you’ve read have been read by other people. And all the songs you’ve loved have been heard by other people. And that girl that’s pretty to you is pretty to other people. And you know that if you looked at these facts when you were happy, you would feel great because you are describing “unity”. It’s like when you are excited about a girl and you see a couple holding hands, and you feel so happy for them. And other times you see the same couple, and they make you so mad. And all you want is to always feel happy for them because you know that if you do, then it means you’re happy, too.
When a crystal gem has a child, that child inherits their gem stone and the parent gives up their physical form for their child. (We already know about this because of the “Laser light cannon” episode)
So each crystal gem gets a gem stone from one of their parents so that means every crystal gem has to lose either their mother or father to be born.
