Matter is the shadow of Spirit and the limitation of Spirit. Matter is an emanation of Soul and forms one of the means through which Soul can understand itself.
"Matter is the vehicle for the manifestation of soul on this plane of existence and soul is the vehicle on a higher plane for spirit" - The Secret Doctrine
This is the cause of the evil we see in our physical world. Evil is the result of the limitation of Matter, which is precisely why Matter is useful to Soul. Matter provides the necessary learning environment which Soul needs in order to grow in understanding and experience.
Such limitation is essential to creation. Limitation is the essence of creativity. Creativity itself is inherently limitation, the Infinite One being already perfect and complete and having no need of creativity.
Limitation then is a natural aspect of manifestation and a critical tool for the Soul to ascend back to the Divine Mind.
"Understanding that all matter is space, and between space is consciousness, that without the consciousness, matter holds no form." - The Zeta
Consciousness and free will are the two most important facts about reality. Consciousness is the primary element and basis of existence. Everything is made of consciousness.
Consciousness is the original, mysterious source of all that is manifest. Consciousness is free, it inherently has free will, although it chooses to limit its free will in order to make experience possible. The limitations of Matter make possible infinite experience by providing the illusion of separation and therefore comparison.
The relationship between the One, the Divine Mind and Soul is made clear when one considers a geometric circle. The One is a point out which emanate the infinite radii of the Divine Mind, all connecting to the outer diameter of Soul.
This originating point of the One is, however, in all places, dimensions and realities simultaneously. This is the origin of the One's Unity. This Unity is the All-Soul and is the source of Love. It is the Soul's desire to understand and reunite with the larger All-Soul that is the very act of Love itself.
But Love also explores the infinite. Love is also desire. Desire is the source of the Divine Mind's creativity. The Divine Mind is consumed with an overwhelming desire to understand all facets of existence and thereby understand itself.
Thus Love is the source of creativity and experience. Love is the manifestation of the primordial Unity of the Unmanifest.
Creativity and Love form the fundamental polarity of separation and unification. This is the essential polarity which consciousness has chosen in order to observe itself from different perspectives.
Separation is what allows for individuation and the creation of new perspectives.
Unification is what allows for all experience to return to Source Consciousness.
We experience this binary in all things: light / dark, matter / non-matter, service to self / service to others, evil / good.
Creation is the separative force. To create is inherently to separate and establish new forms and hence to create new perspectives and possibilities for experience.
Love is the unifying force and since the initial act of creation is separation, reunification through Love is the ultimate goal of all beings.
Love is the movement back up the hierarchy of consciousness, to higher and higher states of being and ultimately reunification with the Source.
Creativity is the formation of infinite perspectives and infinite experience, it is what makes the journey of reunification through Love worthwhile.
"Such limitation is essential to creation. For without a projection of Divine Substance into conditions and limitations - of Being, which is absolute, into Existence, which is relative - God would remain inoperative, solitary, unmanifest and consequently unknown, unhonored and unloved, with all God's power and goodness merely potential and unexercised. "
"For aught else to exist than God, there must be that which is, by limitation, inferior to God."

"Consciousness seeks oneness. Consciousness seeks itself. Consciousness seeks to understand itself."
"You cannot see consciousness. Consciousness can only understand itself in separation."
