The meaning of life.

In order to immediately prevent possible misunderstandings regarding the categorically formulated thoughts, which sometimes do not allow for opposing opinions: Everything stated below is nothing more than a subjective point of view, which is the result of many years of reflection.

Let's start with the fact that there is no meaning in this life.
There is none at all.
Just as there is no happiness in it (in the ordinary sense of Paradise) - but this is already a separate question.

We are free in our choice of meaning. Unfortunately, this freedom has a downside: no matter what meaning you choose, it will not be true, it will not be right, it will simply be yours.

A person lives one single life, at the end of which death awaits him. Nothing will happen next. Nothing at all. The fear of the unknown forces us to invent thousands of illusions.

At the end of life, when there will be a pre-death activation of almost all cells of the nervous system and brain (and this always happens, regardless of how death occurs), you will see your last movie (they also say that your whole life flashes before your eyes), which will last for eternity, since there will be no more time.
Time will remain only for the living. In their watches, not even a second will pass before your consciousness fades away.
As such, time does not exist at all; there is only our subjective perception of time (because we judge time only by clocks, the change of seasons, the time of day, the physical aging of the body, etc. - if we remove all this, what remains? What if we don't measure it, this time?).
Time is just a physical quantity that has nothing to do with our perception of time.

Have you had moments in your life that lasted longer than other hours or even days?
Have you had days that flew by like seconds?
There is no need to even answer; I know that everyone has.

There is no time, and when you die, you will relive your life over and over again for eternity. Or some part of it. Or some of its fragments. But the last memories, as a rule, will be the most vivid, and you will definitely see them.

It is easy to realize this at a rational level and almost impossible to comprehend with your heart. It is impossible to imagine what it is like when I am no more...

It doesn't matter how long you lived, it doesn't matter how. It doesn't matter, in the sense of generally accepted morality, if this morality contradicts your own.
What matters is how you died, and for this, it is important how you evaluate your own life. Did you live in accordance with yourself, with your principles, your morality, your laws?

They say that egoists are the happiest people.
Their internal principles correspond to their instincts. If you are not an egoist (and you cannot remain one without condemning yourself to loneliness), then your internal principles contradict these instincts. You are a neurotic. If not a real one, then a future one for sure. This is what Grandfather Freud said.

I have defined it for myself as follows:
The meaning is to live this life from beginning to end. Not to cling to it and to know its value.
No matter how bad it is, find the strength to endure the reality that does not correspond to us.
And be able to give up it without a shadow of fear in your eyes when the time comes to give up what never belonged to us.

By doing this, you will leave as a winner. It is very important to die as a winner. It doesn't matter what and who you defeated - yourself, your fears, your instincts, you died saving someone, or, on the contrary, killing - it doesn't matter. What matters is that you WON. If you think about it, all the religions of the world teach this.

Do you think a Hero of the Great Patriotic War, who directed his smoking plane at a cluster of enemy tanks, lost?
Do you think a samurai, who overcame all his instincts and slit his stomach in front of other warriors, lost?
Do you think a Christian, who recognized his human weakness and lived according to the commandments of God, who also overcame his own instincts, lost?
Surely, you think that a psych-suicide bomber, stuffed with explosives, who blew himself up in a crowd of people, lost?
And a guy who jumped into the water in an attempt to save a drowning stranger - and drowned himself? It's absurd, isn't it? I attended his funeral. I didn't even know his name and had never seen him before...

NO. In all these cases, they won, if they committed their actions with a clear conscience, without thinking about whether it was right or not, whether it was worth doing or not.

Do what you must - and let whatever happens, happen.
They are Heroes, with a "+" or "-" sign, but Heroes...

Perhaps I am most close to Buddhism in this, although, unlike them, I do not create illusions of reincarnation.
