Duality is the effect of the dual reality of energy & matter.
The duality of energy & matter allows reality to be both physical & spiritual.
Reality is a personal experience that is both physical & spiritual, when perspective is a duality.
Duality allows paradox.
The paradox of physicality & spirituality occurring simultaneously is because of duality.
Duality occurs because physical & spiritual reality are being created simultaneously.
Physicality is the perspective of a human being experiencing a material existence.
Spirituality is the perception of a spiritual entity experiencing being a physical human being.
I can see the world through the eyes of my physical sense of ego Self or I can see the world as a creation of the spiritual entity of my Soul.
Duality is the effect of the experience of choice.
Duality allows choice and duality is relative to choice.
I choose a world of duality because it allows choice.
Once I experience the duality of choice, I can see the singularity of no choice and I can overcome duality with a third way.
Duality is the gateway to the triality of Divine Choice.
The choice of a third way that overcomes duality is always Divine.
