This is a highly beneficial aspect for a romantic relationship, because it signifies positive growth as individuals and as a couple. Through knowing and loving one another, you're both changed for the better. And you just have a lot of fun together!
In fact, the very things that are most beneficial to you as a couple are also really enjoyable -- talking at length about your spiritual values and beliefs; indulging in physical and emotional intimacy... All of that and more comes together to bring you new experiences and generally expand your horizons. This person introduces you to ways of being that you might never have encountered before. In fact, traveling together would be a great way to jump-start that tendency -- you're bound to stumble onto something amazing if you decide to explore the world together. Taking classes or reading books together is also a fun way to connect and learn something as a team. It's not that your viewpoints always merge; it's that you love the process of sussing out what each of you perceives, thinks and feels, and the spontaneous, lighthearted energy that you create together makes both of you feel great! Your partner especially is able to help you recognize opportunities and take them before they disappear. Just be careful not to take this emotional high too far -- you could encourage each other to overdo it and take unnecessary risks because all the good feelings you create obscure the negative possibilities.
