Very informative for a beginner! It makes sense to me that partnership is meant to surpass all our other relationships because we are gonna share so much time together to help each other achieve the tasks of the soul. I think this means that we are evolutionarily going toward monogamy, as we only need one soulmate at a time. We work on ourselves, and then with the help of a soulmate who is so similar yet so different, we expand ourselves even further.
This book is so amazing, full of hope for better relationship! All the suggestions will serve any couple: be humble, open and compassionate.
