Communication
Communication is such a dire need to eliminate the callousness of existence. Only with the mental attempt to eliminate the space that separates us can we bridge that emotional/spiritual gap to truly say you can be with someone for an eternity, for what is existence in physical proximity with a huge emotional and spiritual precipice between you? Nothing but a cold spirit and a callous feeling can be derived from such an experience.
That is not intimacy, but an attempt to secure an imaginary goal of closeness, a feigning of love. Love can not be replicated, it can only be grown from the budding flower that it started to grow, and once it dies it must be re-germinated through a painful process. Communication is the soil, intimacy is the water and trust is the sunlight that blooms the flower of love.
Better to attempt to maintain than to attempt to regrow.
