I hope this message finds you well. I absolutely LOVED your success story regarding how you attracted the love of your life back in your life. Actually, I am in a similar situation and I stumbled upon your story while I was browsing online. And, your story is the only reason why I joined this forum.
I wanted to ask you a few questions. Therefore I added you as a friend and hopefully I will get the chance to message you. I am really sorry to bother you but I hope you don't mind helping me out. Thank you so much.
The absence or presence of greater purpose is as irrelevant as the finality of death. The claim that our lives are 'ultimately' meaningless does not make sense because there is no sense in which they could be meaningful or meaningless outside of how we regard them. Questions about the meaning of life are questions about values. We attribute values to things in life rather than discovering them. There can be no meaning of life outside of the meaning we create for ourselves because the universe is not a sentient being that can attribute values to things. Even if a sentient God existed, the value that he would attribute to our lives would not be the same as the value that we find in living and thus would be irrelevant.
What makes our lives meaningful is that we find the activities we engage in to be worthwhile. Our determination to carry out projects we have created for ourselves gives our lives meaning. We feel that life is meaningless when most of our desires which we regard as important are frustrated. Whether we regard life as meaningful or meaningless depends on the degree to which our important desires are frustrated. The judgments that we make about our lives on these points are the same regardless of whether one's life is eternal or not or whether it is part of a greater purpose or not. Perhaps the secret to a meaningful life is to focus on those desires which we can fulfill and diminish those which we cannot--provided that we know the difference between the two.
 We have no more reason to believe that human consciousness continues to exist after death than we have to believe that water buffalo or other animals continue to have experiences after they have died. Furthermore, we have very strong evidence that consciousness depends on brain functioning and thus mental life ends when the brain dies (see The Scientific Case Against Immortality for a survey of this evidence).
Within the seed of your desire is everything necessary for it to blossom to fulfillment. And Law of Attraction is the engine that does the work. Your work is just to give it a fertile growing place in order to expand.
