Humanity is one integrated body.
We all unite into one spiritual body. Such a spiritual body, where all parts are in harmony with each other is called Adam, the first man. If every person corrects his desires and is ready to unite with the same corrected desires of other people, seeking to unite like brothers into one body, one desire, then we all are connected. And then inside this connection we feel the first man, Adam HaRishon, the joint desire assembled from many private desires.
