"What she writes out needn’t be at all the contents of her own mind — it needn’t be anything she knows — but it’s something that somebody in the room knows, or somebody that she’s very close to knows. And, in this way, two people who are sympathetic to each other and who are right, who are compatible in this sort of spiritual way, in fact make up one person — they make up one source of power, which you both use and you can draw out material in incredible detail from the single shared mind. … It’s not that you choose the same things to write about, necessarily, and you certainly don’t write about them in the same way — it’s that you draw on an experience, it’s as though you knew more about something than you, from your own life, have ever really learned. . .

It’s a complicated idea to get across, because you’ve first of all to believe in this sort of telepathic union exists between two sympathetic people."
