A few years ago, someone left a scathing comment on something I’d written. Three sentences. That’s all it took to send me into a spiral that lasted days. I replayed those words in my head hundreds of times. I composed brilliant responses in the shower. I analyzed every possible motive behind the criticism. I lost sleep over it.

Three sentences from a stranger, and I handed them the keys to my peace of mind for an entire week.

When I later found Joseph Murphy’s teaching on handling criticism, I realized the problem had never been the comment. The problem was what I did with it inside my own mind, the way I took those words and pressed them deep into my subconscious through obsessive repetition. I was doing the critic’s work for them, over and over and over again.

Murphy’s Core Principle: Nothing Has Power Unless You Give It Power

Murphy was remarkably consistent on this point. He taught that no external event, including criticism, has any inherent power over your emotional state. The power comes from your reaction, from the meaning you assign to it, and from the mental repetition you give it afterward.

“No person, place, thing, or condition can disturb you unless you permit it. The only power any external suggestion has is the power you give it through your own thought.”
– Joseph Murphy (1963)

This isn’t the same as saying criticism doesn’t hurt. Of course it hurts. Murphy wasn’t naive about human emotion. But he drew a critical distinction between the initial sting of criticism, which is natural and often unavoidable, and the prolonged suffering that comes from mentally chewing on it for days or weeks.

The initial sting is a reflex. The prolonged suffering is a choice, even if it doesn’t feel like one. And it’s the prolonged suffering that does the real damage to your subconscious mind, because it’s through repetition and emotion that the subconscious accepts new beliefs.

How Criticism Gets Embedded in the Subconscious

Here’s what happens when someone criticizes you and you can’t let it go. Each time you replay the criticism in your mind, you’re essentially re-speaking it to yourself. Your subconscious doesn’t know the difference between someone else’s words and your own. It just hears the content: “You’re not good enough.” “Your work is mediocre.” “Nobody takes you seriously.”

And because it’s being delivered with strong emotion, hurt, anger, shame, the subconscious absorbs it deeply. Murphy taught that emotion is the vehicle that drives thoughts into the subconscious. The more emotional the thought, the more deeply it’s impressed.

So when you spend a week obsessing over someone’s criticism, you’re doing something profoundly self-destructive. You’re using your own emotional intensity to imprint their opinion into the creative medium of your subconscious mind. You’re essentially hypnotizing yourself with their words.

“The suggestions of others have no power to create the things they suggest. The power to create comes from your own acceptance of the suggestion. Refuse to accept it, and it has no power.”
– Joseph Murphy (1955)

The Shift: From Reacting to Choosing

Murphy’s approach to handling criticism wasn’t about developing a thick skin or pretending words don’t affect you. It was about developing a new relationship with your own mental processes, learning to observe your reaction without being consumed by it, and then consciously choosing a different response.

I’ve found this to be the most practical thing I’ve learned from Murphy’s work. Not because it makes criticism painless, it doesn’t, but because it dramatically shortens the recovery time. What used to derail me for a week now loses its power within an hour or two.

The process goes like this:

Step 1: Notice the sting. When criticism hits, feel it. Don’t suppress it, don’t pretend it doesn’t bother you. Acknowledge it honestly: “That hurt.” This takes about thirty seconds.

Step 2: Catch the replay. Watch for the moment your mind starts to loop. This is the critical point, the moment where a natural emotional reaction starts turning into self-destructive mental repetition. When you notice the loop starting, name it: “I’m replaying this. I’m giving this more power by repeating it.”

Step 3: Refuse the suggestion. This is Murphy’s signature move. Silently say to yourself: “I do not accept this suggestion. This person’s opinion has no power over my peace unless I give it power. I choose not to give it power.” Say it firmly but calmly. You’re not fighting the criticism, you’re declining to absorb it.

Step 4: Replace with truth. Immediately follow the refusal with an affirmation of what you know to be true about yourself. Not a defensive argument against the critic, an independent statement of your own worth. “I am growing and improving every day. My work has value. I am at peace with who I am.”

Step 5: Release the person. If you have lingering feelings toward the critic, Murphy would suggest blessing them briefly: “I wish you well and I release you from my thoughts.” This isn’t about being noble, it’s about preventing resentment from taking root in your subconscious.

When Criticism Contains a Grain of Truth

Murphy wasn’t suggesting that all criticism is baseless. Sometimes feedback is valid, and ignoring it would be foolish. The key is learning to extract useful information without internalizing the emotional payload.

I’ve developed a personal test for this. After the initial sting has faded, never while I’m still reactive, I ask myself quietly: “Is there something useful here? Is there something I can learn from this that would actually help me grow?”

If the answer is yes, I take the lesson and discard the rest. If the answer is no, I let the whole thing go. Either way, I refuse to make someone else’s words the soundtrack of my inner life.

This distinction has been incredibly freeing. I can now receive constructive feedback without spiraling, because I’ve learned to separate the useful content from the emotional impact. I treat feedback like mail, open it, take out anything useful, recycle the rest. No need to keep the envelope.

A Practice for After Criticism Strikes

Here’s a practice I’ve used dozens of times when criticism has shaken me. It’s drawn from Murphy’s principles and it works best when done within an hour or two of the event.

Find a quiet place. Close your eyes. Take several slow breaths until your body begins to relax. Then silently walk through these statements, pausing after each one to feel its truth:

“I acknowledge that I’ve been hurt by these words.”

“I recognize that I’ve been replaying them and giving them power.”

“I now choose to stop replaying them.”

“No one’s opinion has power over my peace unless I give it that power.”

“I know who I am. I know my worth. I am at peace.”

“I release this person and wish them well.”

Repeat the last two statements several times, feeling them settle into your body. Then open your eyes and move on with your day.

The first time I did this, I didn’t fully believe every statement. That’s okay. Murphy taught that the subconscious responds to repetition, not to perfection. The more you practice choosing your response to criticism, the more naturally it comes. Eventually, the refusal to absorb other people’s negativity becomes a reflex, just as automatic as the old pattern of obsessing over every harsh word used to be.

The Peace That’s Already Yours

What I’ve come to realize is that my peace of mind was never actually taken from me by critics. I was giving it away, voluntarily, through my own mental habits. Murphy helped me see that the power was always in my hands. Not the power to control what others say, but the power to decide how deeply their words penetrate.

If you’re someone who carries criticism around like a stone in your pocket, turning it over and over until your fingers ache, I understand. I was that person. But you don’t have to keep carrying it. The stone only weighs what you allow it to weigh. And you can set it down anytime you choose.
