You two shared an intensely loving, passionate connection in a past life, and you come together in this one to enjoy more of that intense, positive energy. Just as you did back then, you now support each other in a big way and help each other to follow your dreams. You adopt each other's passions as your own; whatever it is that your partner wants to accomplish in their life, you take it on as your personal quest to make it happen, and they do the same for you.
If your partner has a cause that's important to them, you get behind it as well, and cheer them on as they make advances toward supporting it. If your have a hobby that means a lot to you, your partner takes it up just so that they can share it with you! You both take the relationship seriously, with this influence between you; you see it as a project you're working on together, and you both want to put your time and energy into making it come out as well as possible.
