This work was published in 1976. An “inner voice” dictated the content to a psychologist named Helen Schucman.  Although it’s Christian in tone, many have said that the Course points toward universal wisdom.  I’ll let you be the judge of that.

Here are some quotes:

I am responsible for what I see
I choose the feelings I experience
And I decide upon the goal I would achieve
And everything that seems to happen to me
I ask for and receive as I have asked

Nothing real can be threatened
Nothing unreal exists
Herein lies the peace of God

I rule my mind, which I alone must rule
At times, it does not seem I am its king at all
It seems to triumph over me
And tell me what to think
And what to do and feel
And yet it has been given me to serve
Whatever purpose I perceive in it
My mind can only serve
Today I give its service to the Holy Spirit
To employ as He sees fit
I thus direct my mind
Which I alone can rule
And thus I set it free
To do the will of God

There is no more self-contradictory concept
Than that of “idle thoughts”
What gives rise to the perception of a whole world
Can hardly be called idle
Every thought you have
Contributes to truth or to illusion
Either it extends the truth
Or it multiplies illusions

What would you see?
The choice is given you
But learn and do not let your mind
Forget this law of seeing
You will look upon that which you feel within
If hatred finds a place within your heart
You will perceive a fearful world
Held cruelly in death’s sharp-pointed bony fingers
If you feel the Love of God within you
You will look out on a world of mercy and of love

Reality brings only perfect peace
When I am upset
It is always because I have replaced reality
With illusions I made up

The world that seems to hold you prisoner
Can be escaped by anyone
Who does not hold it dear

When you have learned to look on everyone
With no reference at all to the past
Either his or yours as you perceive it
You will be able to learn from what you see now

Seek not outside yourself
The search implies you are not whole within

It is your thoughts alone
That cause you pain
Nothing external to your mind
Can hurt or injure you in any way
There is no cause beyond yourself
That can reach down and bring oppression
No one but yourself affects you
There is nothing in the world
That has the power to make you ill or sad
Or weak or frail
But it is you who have the power
To dominate all things you see
By merely recognizing what you are

Only your mind can produce fear

You will fear what you attack

No one who loves can judge
And what he sees is free of condemnation

The real world is attained simply
By the complete forgiveness of the old

Teach only love
For that is what you are

When you meet anyone
Remember it is a holy encounter
As you see him you will see yourself
As you treat him you will treat yourself
As you think of him you will think of yourself

Is it an evil to be punished or a mistake to be corrected?

You heal a brother by recognizing his worth

You cannot know your own perfection
Until you have honored
All those who were created like you

There is no journey
But only an awakening

Your task is not to seek for love
But merely to seek and find
All of the barriers within yourself
That you have built against it

With love in you
You have no need except to extend it

Remember that you came
To bring the peace of God into the world

Why wait for Heaven?
Those who seek the light
Are merely covering their eyes
The light is in them now
Enlightenment is but a recognition
Not a change at all

Simply do this:
Be still, and lay aside all thoughts
Of what you are and what God is
All concepts you have learned about the world
All images you hold about yourself
Empty your mind of everything
It thinks is either true or false
Or good or bad
Of every thought it judges worthy
And all the ideas of which it is ashamed
Hold onto nothing
Do not bring with you one thought
The past has taught, nor one belief
You ever learned before from anything
Forget this world
Forget this course
And come with wholly empty hands unto your God
