The Body and Soul of Love
The only difference between the holy and the mundane is that the while the holy is united with and aware of the divine energy that brings it into existence at every moment, the mundane experiences THAT SAME divine energy as somehow SEPARATE from its existence.
This body is thus devoted to the realm of the mundane while the soul to the realm of the holy.
We are simultaneously trying to maintain the experience of separateness (as it is familiar) and overcome it (as it is ultimately not true).
The desire to overcome the experience of separateness while simultaneously maintaining it is called human love.
