The Powerful Law of Thought and Effect: As A Man Thinketh
A man cannot directly choose his circumstances, but he can choose his thoughts, and so indirectly, yet surely, shape his circumstances.
James Allen
Stoicism’s fundamental tenet is to focus on what we can control and give no more energy to things we cannot. Within things we cannot control, we also have the power to control our reactions. This gives us a foundation of peace, direction, energy and wisdom.
As A Man Thinketh expands upon this in a groundbreaking way. Within what we believe we do not control, we actually have a sphere of influence much larger than what we give ourselves credit for. If we utilise this power within the law of cause and effect, we can impact ourselves and the world in far greater ways than we previously believed.
We do not control what thoughts appear in our minds. However, we always have control over which thoughts we give attention to. Developing the skill to give the right attention to the right thoughts will blossom into actions, which invariably leads to consequences. Choosing the right thoughts leads to fulfilment and success. Choosing the wrong thoughts leads to pain and loss. Once we choose the cause, we must live with the effect. Knowing this, we can step back and decide on the future we want without the lure of expectation, desire, and limiting beliefs.
Our Mind Can Either Be A Garden Or A Jungle

If we look into ourselves to find the smallest atoms that make up our character, we can go no more granular than our individual thoughts. Like a flower cannot bloom without a nurtured seed, our character (and indirectly our circumstances) cannot blossom without a nurtured thought. We may not control the spontaneity or the initial influence from a deep-rooted thought, but we retain the unwavering power to control which seeds we choose to grow.
As A Man Thinketh uses the analogy that our minds are like a garden. If we consciously cultivate our thoughts or neglect our minds to run wild, the effects will bear fruit either way. Leaving our minds to grow passively will only grow weeds and poisonous flora. Our understanding and actions within reality will, therefore, be toxified and distorted in direct proportion to our minds. We must consciously tend to our mind’s garden, deliberately uprooting thoughts that harm us and carefully growing thoughts that empower us.
If we abdicate the power to choose our thoughts, we give it to something or someone else. Our worth will become conditioned on an opinion or past event. Our actions and purpose will follow someone else’s expectations of us. The world begins to control us, not us flowing with and guiding the world. Our minds can either be a garden or a jungle. The choice is up to us, its consequences will follow suit.
The Hidden Law of Cause and Effect
Every thought-seed sown or allowed to fall into the mind, and to take root there, produces its own, blossoming sooner or later into act, and bearing its own fruitage of opportunity and circumstance. Good thoughts bear good fruit, bad thoughts bad fruit.

The graphic from the TV show Loki shows the possible outcomes we could have had and the reality we live in within the blue. Each branch represents a thought we could have chosen or disregarded. This thought plants the seed, which blossoms into the next event, and so on. This graphic also works in reverse. We can also trace the origin of our thoughts, the actions and perspectives they inspired, and therefore understand our circumstances in the present.
The Past Reveals Our Lives are Justly Ordered
Our past does not decide who we are in the future, but it can reveal what we are now. We can trace something we are unhappy or fulfilled with to its deepest roots. We will find our actions from the past were undoubtedly caused by our deliberate or passive thoughts, which were planted and allowed to take root before we learned this truth.
By introspection, we can begin to observe the events in our past. Understanding how our actions and, in turn, our thoughts guided our past, we can begin to contextualise and credit this law of cause and effect. There are still many things we do not control (and deserve no more energy), but there is a lot more we have control of than we give ourselves credit for.
The stoics would stress we should not judge our past because these emotions lead to no end other than pointless suffering. Buddhism uses the analogy of a scolding hot rock, which we either keep in our hands or simply release. This judgement is its own thought seed, too, which will inevitably bear the fruit it was destined for. Instead, like in meditation, appreciate the causes, effects and nature of our thoughts by observing our past, and use this knowledge to plant and grow new thought patterns in the present.
The Present is Our Power to Initiate the Cause
A particular train of thought persisted in, be it good or bad, cannot fail to product its results on the character and circumstances.
Thoughts can be deliberate or hidden, but they objectively decide which actions we take because there would be no stem without its seed. In each moment, we decide which thoughts we are going to grow. Of course, there are influences from our minds, especially deep-rooted beliefs and emotional influences from our past. However, these will only define our future if we continue to allow it.
If our minds have grown wild with negativity and distortion, we must consciously try to de-weed them from a neutral perspective, removing emotional ties that resist the uprooting of these thoughts. Then, we can begin planting powerful ones like discipline, gratitude, presence, and wisdom. Thoughts that ground us in reality and empower us will also bear fruit. The law of cause and effect goes both ways.
If we begin to try to alter our circumstances while still nurturing a destructive belief in our hearts, we will only bear the fruit that this belief will yield. We cannot change the effects without ripping out old beliefs and experimenting with new ones. This is where introspection and understanding of this relationship can guide us past initial discomforts. The only focus we should have is the present, as our decisions now will set in motion whatever our future self is rewarded or burdened by.
The Future Will Bear the Fruit of Our Chosen Thoughts
Circumstances grow out of a thought[.] Every man knows who has for any length of time practiced self control and self purification, for he will have noticed that the alteration in his circumstances has been in exact ratio with his altered mental condition.
Allen tells us to experiment and prove to ourselves this relationship rather than just taking his word for it. If we understand the effects our previous thoughts have blossomed into, then although we cannot change the past, we have the everpresent opportunity to consistently alter our thoughts into a new future.
We may believe our thought habits and beliefs are set in motion to a predetermined end, but this is simply not true. Take David Goggins, for example. He was not born with the discipline to complete 4,030 pull-ups in 17 hours, run 135 miles in 24 hours, and become one of the most prominent motivational speakers. At 24, he was 300 pounds (136 kg) and a cockroach exterminator.
The goal is not to measure ourselves to his standard but to show that at any point in our lives, we can practice this law. Like unlearning a bad habit and instilling a good one, we will face resistance from our minds. Knowing this, try practising this law for a week without expectations of yourself. You lose nothing if it does not work, but you can change your life if it does. Push through the emotional discomforts of sometimes deep-rooted habits, and see for yourself the radical changes your life goes through in a short period of time.

One thought seed is the difference for a new chain reaction, a new circumstance, and it will bear its fruit, either good or bad, in direct accordance with this power.
Anchor Your Thoughts within a Purpose
Even if he fails again and again to accomplish his purpose (as he necessarily must until weakness is overcome), the strength of character gained will be the measure of his true success.
The next stage is figuring out what thoughts we should anchor ourselves within. Stoicism advocates that we should anchor our thoughts on what we can control and release the energy on what we do not. The purpose of this is to do the disciplined act now so our future self and others can benefit.
The parable of The Wise and Foolish Builders explains this further. A house (or garden) built on the foundations of rock (objective purpose) will be unshaken by a torrent of waves (negative thoughts or circumstances). However, in a house without foundations (there is no direction to our thoughts), when a torrent hits this mind, the house easily collapses, and its destruction is inevitable.
Allen and the Stoics were also realists. If we radically alter our thoughts now, it does not affect our lives instantly. It can alter our perspective, but it takes deliberate practice and failures to overcome the atrophy of our previous beliefs. Therefore, aligning with a clear purpose provides the straightest path and breathing space to develop the strength needed to cultivate our new lives.
As A Man Thinketh is only 37 pages long, but it continues to be one of my favourite books to inspire positive change. If you want a copy, click this link, which also includes a deeper comprehension of this law within ‘The Mastery of Destiny’.
