All birds and animals exist in pairs. They harmonize with each other in love. Flowers and butterflies relate from two opposite poles, yet harmonize with each other. This reflects the harmonious relationship of heaven and earth. The opposite poles of the universe come into harmony based on love. It’s the same with migratory birds. Birds in the south fly to the north, and birds in the north fly to the south, loving each other back and forth across the regions. In so doing, they center on love eternally. People learn about love through the textbooks in the museum God created.
