This aspect helps foster a feeling of friendship and support between you that helps both of you accomplish something big through your connection with each other, if you put your minds to it. Your partner brings a certain energy to your life, a desire to make those changes you've always thought about but never quite gotten around to yet. They're a huge source of support for you on this journey of yours; you go to them for advice, or just to talk about the changes you're going through, and the whole experience bonds the two of you in a big way.
Their growth process inspires your search for meaning in life, and vice versa. This aspect helps deepen your connection, as friends and as lovers. Philosophically and psychologically, you're in tune with each other on a deep level. You might each choose to do some sort of formalized expansion of the soul during the course of your relationship -- going to psychological counseling, for example, or taking classes in Zen Buddhism or astrology, or whatever best fits your personal needs for expanded horizons. Whatever you do, do something! This relationship offers you a wonderful opportunity that should be taken advantage of, so don't sit on your laurels when you're together.
