The Heart and the Mind are often spoken of seperately. However, the Heart is only a metaphor for feelings and emotions that reside in the Mind. So the two are actually one. The Mind only seeks what it believes that it needs. Love is the goal of the heart. Therefore the mind believes it needs love. Though we are much like animals in the biological sense, are minds are much more complex. I can't believe the Mind seeks Love solely for reproduction of the species. Love must serve some other purpose. I speculate that Love might be a way for two halfs to become whole. Duality reduces. This gives a new meaning to Soul mate. Soul mates being less when alone grow stronger when together. The two complement and complete when together. Essentially becoming one. This oneness achieved on a global scale could be the next step in human evolution. These aren't new ideas really. I think Tantra touches on this in part. Its just come together in my mind while thinking of my other half. I could probably think more clearly if she were here. So I think the search isn't in vain after all.
