We are told in the course that our mind is not the brain, but our spirit which focuses on a situation in the choice of being and experience. To have the experiences, our mind split for a human reality because the choice to focus is on experiences of being human. However, the source to experience being human is also in our mind, not the brain. We are taught, it is the mind of Christ, our creator, along with the spirit of the universal father, with free-will which enables our minds to create as the creator. Although that part of the mind is available to us, the conscious part of the mind is asleep to it. With our spirit is the mind of Christ, which denotes our unity, our oneness. Our human mind expresses our individuality, personality, and conscious guide while experiencing the physical. The course expounds our souls have already been perfected, but our mind has gone insane, now ignorant of its powers, and its abilities to create. Its creations are unknown to itself. So we have been in training, and now is the time to awaken and accept the mind as spirit self to move on; that is to ascend to higher levels of soul's experiencing.
Urantia Papers tells us more stating,
"There is a cosmic unity in the several mind levels of the universe of universes. Intellectual selves have their origin in the cosmic mind..... 111:1.2 (1216.3)
Mind is the human soil from which the spirit Monitor (the Thought Adjuster, a fragment of the spirit of the Universal father) must evolve the ... soul with the co-operation of the indwelt personality. 111:1.1 (1216.2)
On the human level of intellectual selves, the potential of spirit evolution becomes dominant, with the assent of the mortal mind.... But such a spirit dominance of the material mind is conditioned upon two experiences:
This mind must have evolved ... and the material (personal) self (the human or ego) must choose to co-operate [with the indwelling Adjuster] in creating and fostering [the morontia self], the evolutionary and potentially immortal soul.
Material mind is the arena in which human personalities live, are self-conscious, make decisions, choose God or forsake him, eternalize or destroy themselves. 111:1.3 (1216.4)
Material evolution (creation) has provided you a life machine, your body; the Father himself has endowed you with the purest spirit reality known in the universe, "your Thought Adjuster".
But into your hands, subject to your own decisions, has been given mind, and it is by mind that you live or die. It is within this mind and with this mind that you make those moral decisions which enable you to achieve Adjuster likeness, and that is God likeness. 111:1.4 (1216.5)
Mortal mind is a temporary intellect system loaned to human beings for use during a material lifetime, and as they use this mind, they are either accepting or rejecting the potential of eternal existence.
Mind is about all you have of universe reality that is subject to your will, and the soul—the morontia self, will faithfully portray the harvest of the temporal decisions which the mortal self is making.
Human consciousness rests gently upon the electro-chemical mechanism below and delicately touches the spirit-morontia energy system above. Of neither of these two systems is the human being ever completely conscious in his mortal life; therefore must he work in mind, of which he is conscious.
It is not so much what mind comprehends as what mind desires.....
It is not so much what mind is like as what mind is striving to be like, that constitutes spirit identification.
It is not so much that man is conscious of God as that man yearns for God that results in universe ascension.
What you are today is not so important as what you are becoming day by day and in eternity. 111:1.5 (1216.6)
Mind is the cosmic instrument on which the human will can play the discords of destruction, or upon which this same human will can bring forth the exquisite melodies of God identification....
The Adjuster bestowed upon man is, in the last analysis, impervious to evil and incapable of sin, but mortal mind can actually be twisted, distorted, and rendered evil and ugly by the sinful machinations of a perverse and self seeking human will. Likewise can this mind be made noble, beautiful, true, and good—actually great—in accordance with the spirit illuminated will of a God-knowing human being. 111:1.6 (1217.1)
Evolutionary mind is only fully stable and dependable when manifesting itself upon the two extremes of cosmic intellectuality—the wholly mechanized and the entirely spiritualized. Between the intellectual extremes of pure mechanical control and true spirit nature there intervenes that enormous group of evolving and ascending minds whose stability and tranquillity are dependent upon personality choice and spirit identification. 111:1.7 (1217.2)
But man does not passively, slavishly, surrender his will to the Adjuster. Rather does he actively, positively, and cooperatively choose to follow the Adjuster’s leading when and as such leading consciously differs from the desires and impulses of the natural mortal mind. The Adjusters manipulate but never dominate man’s mind against his will; to the Adjusters the human will is supreme. And they so regard and respect it while they strive to achieve the spiritual goals of thought adjustment and character transformation in the almost limitless arena of the evolving human intellect. 111:1.8 (1217.3)
Mind is your ship, the Adjuster is your pilot, the human will is captain. The master of the mortal vessel should have the wisdom to trust the divine pilot to guide the ascending soul into the morontia harbors of eternal survival. Only by selfishness, slothfulness, and sinfulness can the will of man reject the guidance of such a loving pilot and eventually wreck the mortal career upon the evil shoals of rejected mercy and upon the rocks of embraced sin. With your consent, this faithful pilot will safely carry you across the barriers of time and the handicaps of space to the very source of the divine mind and on beyond, even to the Paradise Father of Adjusters." 111:1.9 (1217.4) Click Here to See Related teachings on the mind.
