Can the Mind Be Trained to See Only Good?
Setting the mind as a trap for God.
Paul Simon’s 1970s song, The Boxer, has a line that says, “a man sees what he wants to see and disregards the rest.” It is a lyric that has stuck with me for fifty-five years. It is an observation that stands at the heart of what A Course in Miracles (ACIM) teaches on perception. My own study and practice of ACIM shifted into greater clarity once I realized how the ACIM Workbook lessons leveraged this law of perception to train my mind.
The ACIM Text outlines the intellectual theory of what is possible, but the Workbook is where theory is tested, practiced, and proven. To read the Text is to be persuaded that something greater is possible. To do the Workbook is to see that possibility made real.
Setting the mind as a trap for God.
The idea of "setting the mind as a trap for God" is a metaphor with roots in Aramaic. It does not suggest a hostile or manipulative act but rather refers to the spiritual practice of focusing the mind to become receptive to divine influence. This concept also has implications for intellectual and spiritual growth, the limits of human understanding, and personal devotion.
The phrase "setting the mind as a trap for God" comes from the Aramaic word for prayer, “slotha,” which can be translated as "to incline, bend toward, trap, and capture". In this context, it means preparing the mind, like a trap, to "catch" or receive the thoughts, wisdom, love, and peace of God. Asking for and inviting a response from higher realms. It emphasizes an active, focused state of prayer where one is open and ready to receive divine input, rather than just asking for things. It is intentional and not passive.
Training the new perception.
The Workbook is presented in two parts. The first dismantles the way perception works for beginners. The second introduces what the Course calls true perception. The sequence is deliberate. No new vision can take root while the mind clings to its old habits of judgment, exclusion, and distortion. Undoing must come first. Yet the goal is not destruction but transformation. The very faculty once bent to deceive is repurposed and redirected.
Perception, the Course insists, is always selective. It cannot operate without evaluation, choice, and judgment. Something is always accepted, something else rejected. This selectivity becomes the lever that shifts perception from fear to love.
The lessons ask little of the student—only that the ideas be applied without exception. Belief is not required. Understanding is not required. One need not welcome the ideas or even feel comfortable with them. The instruction is simple: practice them. Proof will follow. This reversal of logic upends the ego’s demand for evidence before action. Here, practice comes first, and proof grows out of practice.
The Course explains that the body was fashioned as an instrument of deception, a device to make separation seem real and God absent. Its senses report weakness, threat, hunger, sickness, and death. Yet once the mind chooses truth as its aim, these reports can change. The senses begin to notice peace, healing, the hidden power of love at work in the world, and miracles. The form of perception may remain the same, but the content shifts. What once appeared a trap set against God becomes the very snare in which His presence is revealed—not because He was absent, but because the mind has learned to notice Him everywhere.
Messengers of perception.
Hence the Course’s frequent talk of witnesses and messengers. These are not external beings dispatched from afar but personifications of perception’s selectivity. The mind sends them forth, and they return with reports. Guided by the ego, they bring back evidence of fear. Guided by the Holy Spirit, they return with confirmations of love. They never betray their commission. The Workbook is training in how to send different messengers and welcome their return.
The process is clear and convincing. A lesson may ask the student to see a brother as innocent rather than guilty. At first this feels artificial. Yet through repetition, perception shifts. The mind begins to notice small signs of kindness or patience once overlooked. The messengers have been redirected, and they bring back new testimony. The brother has not changed; perception has.
Use Lesson 240 as an example. “Fear is not justified in any form.”
“How foolish are our fears! ²Would You allow Your Son to suffer? ³Give us faith today to recognize Your Son, and set him free. ⁴Let us forgive him in Your Name, that we may understand his holiness, and feel the love for him which is Your Own as well.”
This is no passive exercise. The Workbook involves repeated asking—for light, for help, for a new way of seeing. Asking signals willingness, and willingness dispatches new messengers. By focusing our intention on Lesson 240 and desiring an experience of the truth, we prepare our mind to notice how our world responds to the request.
When we ask to be shown that our fears are unfounded, we will be presented with a fearful event or circumstance, and then shown that the fear has no foundation. If we are overwhelmed by the fear and refuse to see past it, the lesson may be lost. A study of the Text helps prepare one for the Workbook lessons.
“Now you have reached the turning point, because it has occurred to you that you will gain if what you have decided is not so. Until this point is reached, you will believe your happiness depends on being right. But this much reason have you now attained—you would be better off if you were wrong.” ACIM OE Text 30.21
One need not understand how the shift occurs, only that it does. Daily practice cultivates this reflex, teaching the mind to pause before judgment and request another vision.
Gradual growth
The change may be gradual. Perception forms a feedback loop: the more one asks, the more one sees; the more one sees, the more one believes; the more one believes, the more one asks again. Slowly the balance tips until the case for truth outweighs the case for illusion. What once guaranteed deception now assures revelation.
To call this a “trap for God” is not hostility but inevitability. The ego set a snare to prove separation by focusing perception on its evidence. The Holy Spirit turns the same device into a net that catches His presence. God is not trapped, but the mind is trained to glimpse Him in every direction.
The genius of the Workbook lies in its simplicity. It asks not for advanced understanding but for use. Resistance, hostility, and indifference. None of these impairs its power. What matters is application. Truth needs no defense; it only waits to be invited, and once invited it brings its own proof.
In time, the mind discovers that perception is not fixed. It is a tool, not a fact. And once this is known, everything changes. Fear no longer dictates what must be seen. Messengers of love appear, bearing witness to forgiveness. What was once the ego’s fortress becomes the altar of God.
To set the mind to see only good is to consent to this reorientation. It does not deny pain and cruelty but refuses to grant them the final word. It trains the mind to notice the overlooked, to register gentleness, to recognize innocence where blame seemed absolute. As these witnesses accumulate, the picture of the world shifts. A new world dawns, not newly made but newly perceived.
A synthesis of meanings
Ultimately, the image of “setting the mind as a trap for God” may be approached from several angles without losing its unity. It can be read as a description of mystical prayer, in which the mind bends itself toward receptivity and becomes a vessel for divine insight. It can also be seen as a kind of philosophical inquiry, an acknowledgment of the intellect’s attempt to grasp the nature of the divine and, in the process, to discover the mystery that lies beyond comprehension. Most intimately, it can be practiced as personal transformation, the daily yielding of thought to God so that divine wisdom may shape perception and guide the mind into peace.
The closing movement of the Workbook is lyrical because it points beyond itself. Its lessons end not in mastery but in surrender. The mind has been trained, its selectivity redirected, its perception refined. What follows is not the student’s doing but revelation itself. At last the striving ceases. The messengers return, the witnesses testify, their voices joining in a single chorus of certainty.
And here words fall silent. The trained mind, seeing only good, looks upon the world and beholds the face of Christ reflected everywhere. The trap has been sprung. The witnesses have spoken. The messengers have returned. And in their testimony is one truth only, sung without exception: God is here.
