This document discusses how love develops between two people. It explains that love is based on self-hypnosis, where each person develops their own imagination and ideas about the other based on limited interactions. These feelings are strongest when the individuals are apart and able to think about and wonder about each other. For love to develop, it is important to give the other person space and uncertainty rather than always being available, as humans are more likely to dream about something uncertain rather than something they feel is guaranteed.
