The wisdom of Uncle Pom

Uncle Pom: Sheeta, I must tell you something.

Sheeta: Yes? What is it?

Uncle Pom: That crystal is extremely powerful, but with a power that rightfully belongs to the Earth from which it came. To forget that and then to try to use the crystal’s power for selfish reasons will bring great unhappiness. Do you understand?

Sheeta: Yes.

Uncle Pom: Your crystal should remind us that we come from the Earth, and to the Earth we must return.
