When you have a history with a person, you get in a dangerous rut. Not dangerous in terms of your safety, but in terms of your soul’s growth. The his-story and her-story between you keeps you focused on what came before and what you think will come in the future based on what came before. That story, in your human mind, must continue unfolding in a certain way, and the human mind loves to build upon the past.
What if your relations with that other were based solely on this moment now? How might you see them differently based on what you know now as a soul? There would be no history, and hence no expectations. See what happens, why don’t you, when you meet one anew over and over and over again.
