We confuse the ecstacy we experience in sexual interactions with the person, and begin to idolise this person, worshipping him or her with all your heart—something today we call true love. But the truth of the matter is that we should be focusing on the feeling of ecstacy of the moment and not the object that stimulated the experience, stemming for your desire, igniting your energy to reach these ecstatic peaks—only to wither away, sometimes slowly, sometimes rapidly, descending into the dark valleys between the peaks, where most of the time we reside—with all its mundane, that is, non-ecstatic, tasks, needs and responsibilities, while, all the time, longing for that feeling of ecstacy which has been lost. This loss will incite you to spend much time and energy on either coming to terms with it or, more likely, to spend yourself on trying to reignite that same feeling of transcendent ecstacy, that is often confused as love.

This is all about worshipping the representation of the Divine in the person you love. There is the physical manifestation, the template of which is made by G-d, which you do have a significant influence over. The feeling it arouses is primarily one of lust, desire for an object, as it should, due to the need to procreate. Then, if it is to approach love, there needs to be a recognition of the Divine aspect of that particular person, his soul. Thus in order for there to be true love, there has to be a soul connection.
The ultimate love, though, is the love of the Divine Beloved. Whether it is through one’s love for one’s beloved, one’s soul-mate, or not, is insignificant, but it is the love of G-d, who will never stop loving you!
The only one who can be your true beloved is the one who is always with you. Who constantly feels your heart’s desire, and thinks your thoughts with you — the Shekhinah, the Divine Presence immanent in everything we are and everything we (can) do.
