I've already posted a number of things about gentle union. On this video you can see the position again. I also mention two healing exercises that you can do together in this united position.
Regularly practiced gentle union is true peace work. The heart for each other becomes wide and open and the relationship demons such as accusations, blame, bossiness or arguments have hardly any surface to attack. They are shrinking more and more. And if you practice regularly, they can even disappear from your life altogether.
Isn't that motivation enough to start?
