所有的疾病都是自己創造出來的（All illness is self-created.）。現在即使是傳統的醫生也看出人們是如何讓自己生病的。
這是因為，大多數人都是無意識地在過生活 —— 不僅只是健康上的議題與各種後果。
人類彼此競爭 —— 無情地，並且在不可置信的壓力下 —— 卻奇怪他們為何會中風。
而那不怎麼明顯的真相是，大多數的人是他們讓自己擔憂致死（most people worry themselves to death）。
擔憂幾乎可說是最糟形態的心理活動 —— 僅次於怨恨，怨恨是極具自我毀滅性的。擔憂是無意義的。它是被浪費的精神能量。它也創造出傷害身體的生化反應，產生從消化不良到 心肌梗塞，以及在兩者之間的所有疾病。
當擔憂停止時，健康幾乎會立即改進（Health will improve almost at once when worry ends.）。
擔憂是一種「不了解它與我的相連關係」的心智活動。（Worry is the activity of a mind which does not understand its connection with Me.）
恐懼是你們所是的一切之相反面（Fear is the opposite of everything you are），因而對你們精神和身體的健康有反面的影響效果。恐懼是放大 了的擔憂（Fear is worry magnified.）。
擔憂、憎恨、恐懼 ——和它們的分支：焦慮、悲痛、不耐煩、貪婪、苛薄、批判和譴責 —— 全都在細胞層面攻擊身體。在這些情況下，不可能有一個健康的身體。
同樣地—— 雖然是較小的程度 —— 自大、任性和貪心，也會導致身體的疾患或不適。
所有疾病最先都是在心智裡創造的（All illness is created first in the mind.）。
摘自《與神對話 I 》第13章
Neale: How can I solve some of the health problems I face?
Now let's understand what you probably already know: all illness is selfcreated. Even conventional medical doctors are now seeing how people make themselves sick.
Most people do so quite unconsciously. (They don't even know what they're doing.) So when they get sick, they don't know what hit them. It feels as though something has befallen them, rather than that they did something to themselves.
This occurs because most people move through life—not simply health issues and consequences—unconsciously.
People smoke and wonder why they get cancer.
People ingest animals and fat and wonder why they get blocked arteries.
People stay angry all their lives and wonder why they get heart attacks.
People compete with other people—mercilessly and under incredible stress—and wonder why they have strokes.
The not-so-obvious truth is that most people worry themselves to death.
Worry is just about the worst form of mental activity there is—next to hate, which is deeply self destructive.
Worry is pointless. It is wasted mental energy. It also creates bio-chemical reactions which harm the body, producing everything from indigestion to coronary arrest, and a multitude of things in between.
Health will improve almost at once when worrying ends.
Worry is the activity of a mind which does not understand its connection with Me.
Hatred is the most severely damaging mental condition. It poisons the body, and its effects are virtually irreversible.
Fear is the opposite of everything you are, and so has an effect of opposition to your mental and physical health. Fear is worry magnified.
Worry, hate, fear—together with their offshoots: anxiety, bitterness, impatience, avarice, unkindness, judgmentalness, and condemnation—all attack the body at the cellular level.
It is impossible to have a healthy body under these conditions.
Similarly—although to a somewhat lesser degree—conceit, selfindulgence, and greed lead to physical illness, or lack of well-being. All illness is created first in the mind.
