Claim. The spirit world is operated by love the way the physical world is operated by electricity; love is the substrate that lets thought materialize as substance there.
Elaboration. SMM gives the analogy plainly: “the spirit world is the world filled with the electricity of love. There is nothing we cannot do with the electricity of love. Hence, we can say that the spirit world is a realm we can govern by our way of thinking” (2.6. What kind of place is the spirit world?, 112-16, 1981.3.15). The same source describes “love bulbs” that light up the heavenly kingdom: “As long as you keep a loving heart and pull the rope of love, everything will follow.” Food, clothing, and movement are not produced by industry but by love-actuation: “you eat the food of love in the spirit world. You look at each other with the eyes of love.” This reframes spirit-world physics: nothing is mechanical, everything is responsive to true love and inert to its absence. People who cannot transmit love cannot move, eat, or be received there.
