"Dasan's Last Habit" is an old book of advice I've prepared to spread and lean on when the doubt that I've become hardened and empty turns into depression.
Jo Yoon-je, author of 『Dasan's Last Study』 and 『Millennium of Internal Strength』, has selected 57 key passages from 『Sohak』, the study that Dasan began anew after emptying his mind of 60 years of internal strength at the end of his studies, and has interpreted them to suit today's sensibilities.

Small mind and body
The first principle of demonstration is to be timid and timid, and not to be harmed.
These words of Dasan speak of external strictness.
The teaching is that if you are well-prepared on the inside, it should be able to show on the outside.
A person who has deep self-cultivation but cannot express it appears rough.
But a person who is flashy on the outside but not well-prepared on the inside ends up deceiving even his own life.
A person can be called a mature adult only when his or her inside and outside are well-matched.
Just as the appearance of a gentleman is not something that can be achieved through decoration, Dasan's words to his sons are not teachings to decorate their appearance.
This is the natural behavior of a person who knows that their life is a learning experience and that everyday life is a learning experience.
If you want to achieve something, it must be based on daily faithfulness.
If these things accumulate and pile up, they can create results that are difficult to imagine.
When ordinary daily life accumulates and becomes extraordinary, we say, 'Great.'
---From "All the little things in daily life are my teachers"

From inside to outside, from the beginning to the beginning, from the beginning to the end? 灑掃室堂及庭布席各從其庋

Wake up in the morning, shake off the annoyance, and make the bed.
It was a small thing, but it got me going from the start of the day.
If you win the first time, you will win the second time, and as you gain experience in winning, beating yourself becomes a habit.
If you look back at the small details and find solutions, your chances of overcoming difficulties will greatly increase.
The starting point is to simplify your life, stop doing what is wrong, and do your best in the daily routine given to you.
As Confucius said, any lofty ideal must begin from the ground.
It would be ridiculous for a person whose entire family is immoral to cry out for social justice.
No matter how high your ideals are, they begin with you standing on the ground in reality.
And it is a daily life that you create.
Nothing can be accepted unless it is proven in everyday life.
---From "If you want to change the world, start by organizing your desk"

Confucius's foreign affairs, his love and sorrow, his friends, his family, his hometown, his hometown, his hometown, his hometown, his hometown, his hometown, his hometown, China, etc. The story of the great man
Confucius's Confucianism is pure and innocent, and the person who cannot speak is the one who cannot speak. The person who cannot speak is the one who cannot speak. The person who cannot speak is the one who cannot speak.
We often envy the ability to express our opinions as freely as water.
However, speaking in a showy manner, using a lot of miscellaneous knowledge and technical terms, cannot be considered true speaking ability.
The same goes for using complicated expressions or mixing foreign words in your speech.
To these people, Confucius taught, “Words are enough to convey meaning (辭達而已矣).”
It is a pity that words have been decorated but their meaning has been lost.
If you speak when you should, refrain when you shouldn't, and speak sincerely without hiding anything, that's enough.
The same goes for behavior.
You must act confidently, knowing when to step forward and when not to.
But above all, there is something that must be protected.
Whether in words or actions, respect for others must be the foundation.
---From “Words are enough if they convey the meaning properly”

Do you think about it? Do you think about it? Don't worry about it. Don't worry about it. Don't worry about it. Don't worry about it. Don't worry about it.
Zengzi said, "The octopus is not capable of anything, it is a octopus of the same species, and it is a medicinal herb. It is a real medicine. It is a Buddhist stone. It is a five-character, five-sang, and five-faced monk. It is a royal inspector."
As humans, we all have shortcomings and limitations, and we cannot be exceptions to this.
A great person recognizes his own limitations as well as those of others.
However, people who are obsessed with blaming others for their mistakes often fail to see their own shortcomings.
“A gentleman develops others’ strengths and prevents their weaknesses,” is written in the Analects of Confucius.
As the saying goes, “The small person does the opposite.”
The answer to interpersonal relationships that Dasan talks about is the same.
I taught my two sons that they must be able to give first.
“If you expect others to approach you first, it is because your arrogance has not yet been eliminated.” This is a criticism that the desire to hold others to strict standards that you cannot apply to yourself is a sign of a lack of self-cultivation.
He who would embrace today must be able to embrace yesterday's mistakes.
---From "Everyone is walking through hell, so be generous to others"

勿以惡小而爲之 勿以善小而不爲
Water is evil, water is good, water is bad
When Jang Goae was the magistrate of Sungyang County, he caught the warehouse keeper stealing a penny.
When Jang Go-ae punished the warehouse keeper with a beating, the warehouse keeper complained, “How can you beat me for a mere coin?”
Then Jang Goae said, “One penny a day becomes a thousand penny in a thousand days.
He was punished, saying, “Just as a rope can cut a tree, and water can wear away a stone.”
In 『Sohakjieon』, Dasan also revealed the source of the warning that “one should not do evil because it is small, and one should not not do good because it is small”, saying that it came from the “Gyesajeon” of the 『I Ching』.
When faced with minor evils in everyday life, it is not easy to remember the obvious principle of 'be a good person!'
Evil is so easy and common.
But villains don't just appear one day.
---From "Evil Wears the Mask of 'Ordinariness' and 'Triviality'"

常持四字勤謹和緩
Since the hat and water pipe, the upper limbs of the lion and the upper limbs of the lion are close and close together.
When the emperor first came to see Dasan, he said this.
“Teacher, I have three shortcomings.
“You are too dull, too blind, and too incompetent.” Then Dasan taught you this.
“There are three major problems for learners.
First, people who see something once and memorize it quickly forget it because they do not savor its meaning.
Second, even if you just throw out a title, the writer may be smart, but the writing will be light.
Third, people who understand something quickly with just one word do not chew on it and therefore lack depth. There is no need to rush to show something right away.
There is also no need to be anxious about short-term performance.
The reason why characters that were initially bright and shining suddenly disappear is all due to impatience and impatience.
It is not advisable to be overly excited or depressed by immediate results in any matter.
The person who quietly carries out the work assigned to him and consistently improves himself will ultimately win.
What matters is not speed, but direction.
And consistency.
If you can keep going in the right direction without stopping, things will eventually get done.

---From "Because it is slow, the direction is certain, and because it is heavy, the footsteps are deep"
