The real key to love and happiness is to understand the other person. Completely understanding them gives us a chance to help them and love them as they are. This is true for all kinds of relationship.
The love that I feel for my husband is based on this understanding. A reverence for the other person definitely helps in transcending the boundaries of me and him. We become one in the moment of deep joy, reverence and love. The core of the relationship is understanding. Respect and understanding should be deep in the heart and not necessarily in the words. Any fool can say anything but the deep feeling should arise in the heart. At that moment, we become one with our spouse.
