It is your thoughts alone that cause you pain

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.

~ Jesus, A Course in Miracles

Accept not suffering

Illusion recognized must disappear. Accept not suffering, and you remove the thought of suffering. Your blessing lies on every­one who suffers, when you choose to see all suffering as what it is. The thought of sacrifice gives rise to all the forms that suffer­ing appears to take. And sacrifice is an idea so mad that sanity dismisses it at once.

Sustaining this harmony will keep your body in perfect health

The mind, once released from the ego’s thought system, has but to relearn the thought system of the truth. Your mind, heart and body have joined in alignment to bring this learning about. They now exist in harmony.  

Your mind and heart in union have brought harmony to your body.  Sustaining this harmony will keep your body in perfect health, even while the manner of this perfection of your health will remain one of many options. 

Jesus, A Course of Love T4.7.6
