In the Heart Sutra, which expands the idea of ​​publicness, it explains in various ways, especially based on the 'Five Aggregates'.
They say that if you just know that 'Oh-on' is 'empty', you can cross the sea of ​​suffering.
Furthermore, it tells us that there is a hollow truth in all the discriminatory delusions we create while living.
These are unfamiliar words, so they may seem very difficult to those who are hearing them for the first time, but if you just change your mindset, it's not that difficult.

This phenomenal world we live in has no substance, as it was created by fate and then disappeared in the blink of an eye.
Knowing that the world has no substance is called Prajna wisdom, and it contains the content that through this wisdom one can cross the sea of ​​suffering.

They say there is no better lesson in life than your own experiences.
Even so, Prajna (wisdom) transcends everyday wisdom.
Prajna is the wisdom that removes obstacles like water that flows naturally.
Moreover, Prajna does not simply refer to the acquisition of information.

The reason is that it is fundamentally wisdom that is free from the three poisons of greed, anger, and ignorance.
Therefore, this wisdom gives the power of insight.
In early Buddhism, wisdom based on the Four Noble Truths, which are suffering, the cause of suffering, the cessation of suffering, and the path leading to that cessation, was called 'prajna.'
And the Buddha always guided us on the path of wisdom.
Here is the way to end suffering, so don't suffer anymore!

In fact, there are many things you can know just by looking at someone's appearance.
There are things you can tell by looking at what the face looks like and whether the limbs are long or short.
If we delve a little deeper into it, we can grasp the emptiness through the revealed appearance called 'color'.
The human body, represented by 'color', is a product of karma created by fate or karma.
Just because you look like this now, it doesn't mean you'll always look like this, and it's impossible that you were like this in your past life.
The appearance is not always the same.
Just by looking at this, you can find the 'emptiness' through the flesh.

From the time we were born until now, we have existed in a constant state of causality.
The precious relationships we make are all the result of the time and sincerity we pour into each other.
The union of my parents was a bond of fate, and my upbringing and other circumstances were also bonds of fate.
Because of this, none of the feelings, thoughts, intentions, or perceptions that we each accept at any given moment are fixed.
‘Number, appearance, action, and consciousness’ are also impermanent because they are the result of a combination of causes and conditions.
The sayings, “Receiving is emptiness,” “thinking is emptiness,” “action is emptiness,” and “consciousness is emptiness” are also based on this same principle.

Here is a clear mirror that allows us to look deeply into everything.
Let's take a look at ourselves in this clear mirror.
Everything that is reflected is an appearance that appears according to fate.
When we look at them from the perspective of the ball, they transcend dirt and cleanliness.
However, our minds are bound by distinguishing and discriminating against the revealed phenomena.
By evaluating and discerning ourselves, we actually bind and are bound.

I like flowers.
No one would dislike the sight of a beautifully blooming flower, but in reality, a flower is just a flower.
If the environment is right, flowers bloom and fall in due time, and they do not intend to show off to anyone.
Whether a flower is pretty or not is a result of the viewer's discernment.
So, there is no problem with the ‘color’ itself called a flower.
The question is whether I am captivated by flowers or not.
Likewise, originally, everything in the world is equal, but discrimination arises because those who deal with it lose their sense of equality and become unstable.
It's all a matter of the person who creates the discernment.

Ignorance, formation, consciousness, name and form, six sense bases, touch, feeling, desire, grasping, existence, birth, old age and death.
Even in this twelve links of dependent origination, it is said that everything from the nameless one at the very beginning to the old one at the very end is non-existent.
Why? From the perspective of the public, all laws of karma—that is, everything from natural karma to death—contain emptiness.
Things that are temporarily combined produce some result, but they are not even the cause.
Everything that dies becomes the seed of something else, but all of that, according to the logic of the universe, is said to be nonexistent.

Just as a shoe fits perfectly and you don't even realize you're wearing it, life is not full of pain or anger.
There is nothing to gain or lose.
However, if the shoes are too big or too small, you will constantly be concerned about your feet.
It's like feeling uncomfortable and irritated even if just a few grains of sand get in.
Everything in this world is like that.
It has to be just right so that you can forget it without even realizing it.
--- p.256

Everything is created from me when my muscles and the object meet.
When I realize that everything is empty, we have nothing left to worry about.
Because you know that there was no relationship in the first place, you gain freedom from everything.
The story goes that if you realize that your nature is empty, you will not be disturbed by anything.
Just like those monks and Buddha did!
