Love is all there is.
The pull of one massive object in space affects another object. Gravity. Or crude, primal love...
The light from the sun affects and inspires all living things to thrive. UV radiation. Or simple, honest love.
The instincts that drive all creatures to multiply. Desire for life. Or savage and beautiful love.
The feelings humans have toward eachother, that enable us to kill eachother and that inspire romance and this crazy mood I am in now. Chemicals. Or complex and mystical love.
The universe is the interaction between visible forces and invisible. Matter and spirit. Crude in its simplest form, but as the wheel of evolution turns it becomes more complex, and each new creation is a more intricate weaving of the spiritual and the material forces. In humans it is so complex that we ourselves cannot always see it. But it is love. It is god.
No matter how great you are, love will always be greater. It is the fuel on this fire, and the reason we exist. It is the question and the answer. It is everything, and if you know it unconditionally you are truly free...
