Some books give you information you didn't have before. Others make you notice something you have been doing for years without realising how much it affects you. The Power of Your Subconscious Mind by Joseph Murphy was the second kind of book for me.
The basic idea of the book is simple: much of what we think, expect and repeatedly tell ourselves eventually becomes part of the way we move through life. Murphy describes the conscious mind as the part that chooses, reasons and makes decisions, while the subconscious mind accepts the ideas that are repeatedly impressed upon it and influences our habits, reactions and behaviour.
Murphy takes that idea much further throughout the book. He connects the subconscious mind with health, relationships, money, success, fear and even physical healing. Some of his claims are much bigger than I would personally present as fact, and you don't have to accept every example literally to find value in the book. What stayed with me was something much more practical: we spend an extraordinary amount of time telling ourselves stories about who we are, what we can expect and what is possible for us, and then we rarely question how those stories affect the choices we make.
The things we repeat without noticing
When people hear about affirmations or positive thinking, it is easy to imagine someone standing in front of a mirror repeating that she is rich, confident and successful while her actual life remains exactly the same. That isn't the part of this book that interested me most.
I became much more interested in the statements we repeat when we aren't trying to practise anything at all.
“I've always been terrible with money.” “I never finish anything.” “Nothing ever works out for me.” “I'm not confident enough to do that.” “People like me don't make that kind of money.” “I always choose the wrong person.” “I can't change. This is just how I am.”
We often say these things as though we are simply reporting facts about ourselves. After enough repetition, they begin to feel less like opinions and more like descriptions of reality. Then we start making decisions that fit them. Someone who believes she never finishes anything may hesitate to begin something ambitious because she already expects herself to quit. Someone who has decided she is bad with money may avoid learning about it because the conclusion about her ability has already been reached.
The thought does not magically create the outcome. But it can influence what we notice, what we attempt, what we avoid and what we expect from ourselves. Over enough time, that matters.
Your mind hears you on ordinary days too
One of the reasons Murphy's ideas stayed with me is that they made me think differently about the casual way we speak to ourselves.
Most of us would recognise deliberately cruel self-talk. We know that standing in front of a mirror every morning and telling ourselves that we are useless probably isn't helping anything. The quieter versions are easier to miss.
You make a mistake at work and immediately think that you aren't good enough. You see a photograph of yourself and spend the next five minutes listing everything you dislike. You have an unexpected expense and decide you will never get ahead financially. You miss a few days of a new routine and turn it into proof that you have no discipline.
The event itself might last five minutes. The conclusion you draw from it can stay much longer.
This doesn't mean pretending that everything is wonderful when it isn't. If your finances are a mess, repeating “I am wealthy” doesn't pay a bill. If you are unhappy with something in your life, positive thinking alone doesn't change it. But there is an enormous difference between recognising a problem and turning that problem into an identity.
“I haven't managed my money well” leaves room for learning.
“I am terrible with money” sounds permanent.
That distinction seems small until you notice how often you make it.
Why affirmations started making more sense to me
I used to think the interesting question about affirmations was whether repeating a sentence could somehow make that sentence come true. After reading books like this, I think there is a more useful question: what happens when the language you repeatedly use about yourself begins to change?
An affirmation doesn't have to be an outrageous claim that your mind immediately rejects. In fact, I find the believable ones much more useful. “I am learning to trust my decisions” gives you somewhere to go. “I can become better at managing money” creates a different possibility than “I will always struggle with money.” “I am becoming someone who keeps promises to herself” can influence what you decide to do when you are tempted to abandon one.
The words still require behaviour. If I tell myself I am becoming disciplined and repeatedly choose not to do anything I promised myself, the sentence isn't doing much work. But if the sentence changes the way I see myself enough to make one different decision, and that decision gives me evidence for the new belief, something begins to shift.
That relationship between thought and action is much more interesting to me than the idea that thinking alone controls everything that happens.
Be careful what you turn into a prediction
Murphy spends a lot of time discussing expectation and belief. Again, I wouldn't interpret that to mean that every bad thing that happens was somehow created by the person experiencing it. Life contains illness, loss, accidents, other people's decisions and circumstances we simply cannot control. I think any philosophy becomes dangerous when it starts making people responsible for every painful thing that happens to them.
But there are areas of life where our expectations influence us more than we realise.
If you enter every new opportunity expecting rejection, you may behave differently. If you are convinced a relationship will fail, you may interpret ordinary problems as confirmation. If you assume people are judging you, you may become quieter and more guarded around them. If you expect yourself to fail, quitting early can feel almost reasonable because it matches the ending you already imagined.
Sometimes we call this realism when it is actually repetition.
That was one of the questions the book left me with: how many things do I believe because they are true, and how many feel true because I have repeated them for years?
I still think about that.
This isn't a book about pretending life is perfect
There is a version of positive thinking that I don't find useful at all. It asks you to ignore anger, grief, fear and disappointment and replace every uncomfortable thought with something cheerful. Real life doesn't work like that, and I don't think becoming a healthier person requires pretending it does.
What I took from The Power of Your Subconscious Mind was almost the opposite. Pay more attention, not less.
Notice what you say to yourself after something goes wrong. Notice the assumptions that appear before you try something new. Notice which descriptions of yourself you keep repeating even though they may have been formed years ago. Notice when a temporary situation becomes a permanent statement about your future.
You don't have to replace every negative thought the second it appears. Sometimes simply noticing that a thought is not automatically a fact is enough to create a little distance from it.
And from that distance, you can decide whether you still want to keep repeating it.
Would I recommend it?
Yes, with one condition: read it with your own judgement switched on.
The Power of Your Subconscious Mind was first published decades ago, and there are parts of it I would take as philosophy rather than science. There are claims and stories in the book that I wouldn't use as proof of what the human mind can literally do.
But I don't need to agree with every page of a book for it to change something in me.
This one made me much more aware of the language I use when I talk about myself, particularly the things I repeat so casually that I no longer recognise them as beliefs. It also made affirmations more interesting to me, not as magic sentences that deliver whatever I ask for, but as one way of deliberately choosing which ideas I want to reinforce instead of leaving that process entirely to habit.
If you are interested in mindset, affirmations, old beliefs and the way your inner conversation can influence how you behave, I think it is worth reading.
Just don't read it because you expect your subconscious mind to do all the work for you.
Read it, perhaps, because it might make you notice how much of that conversation has been happening already.
