Is my interpretation of the Heart Sutra correct?

If you learn not only the Heart Sutra, but Buddhism as an academic discipline, there is no salvation there.
You must put it into practice and experience for yourself that this is really the case. It's about doing your own ascetic practices and verifying whether what you've learned in the Heart Sutra really works.
To that end, it is important to understand and know yourself well. You don't know this as knowledge; you know it as actual experience.

Close your eyes quietly and memorize the spell “hey hey hey...” in your mind.
At that time, various distractions and delusions come to mind one after another so as to interfere with concentration on “that's crazy.”
It floats up and then disappears.
Everything is like a dream or illusion, in other words, the sky.
Everything I can think of in my head is trash that interferes with “that's crazy.”
For those of you who try to focus on “yay gyo tei,” everything is something unworthy of obsession, an empty illusion.
Now let's get back to everyday life.
In everyday life, there are times when, for example, we brush our teeth instead of “yay gaiyatei.”
At that time, distractions other than brushing teeth are the same as trash that interferes with eating, and they are trash.
For ascetic practitioners, living may be about carefully doing “gyatei” on the spot and throwing away distractions that interfere with “gyatei,” saying “it's empty, not worth obsession,” and throwing them away.

Hello. Heart Sutra rather than three times a meal.
I'd like to say... but after all, I love the three times meal “No more meals? You just ate it, didn't you? huh? I'm hungry again (Makaban-yaharamita-shinky),” he says Tange.
The Heart Sutra is an espresso of the Great Heart Sutra.
It's human sama that makes me want to sum it up in one word: the teaching of the sky, the teaching of nothing, the disappearance of me, the important thing is that the sky is the color, selflessness, selflessness, gattegatte.
I know very well that you would like to say that too.
Bottom line: don't try to sum it up in one word.
Because of the Soto sect, there was an Aho-sama who summed it up in one word, “zazen is just meditating” and “it's mukusho zen,” so it's still being misunderstood by the public and is in trouble even internally. Apart from that, Dogen Zenji didn't say “just sit down,” and even though he said “sit down and get physical and mental loss (enlightenment),” Karatsubo scholars trimmed them without permission and made them smaller, and as a result, they died and became zazen. There is such a thing.
The teachings are infinitely interspersed, and of course all are important.
〇Living wisdom
with
〇Knowledge of the head
I think it's a good idea to keep in mind that it's something different from.
There are so many books explaining the Heart Sutra in the world that I think it will be about the height of Mt. Fuji.
However, it is fine to read it and intellectualize and interpret it, but what is important is that it really saved Kaina from life, old age, illness, and death.
Great teaching, great wisdom, let's learn by reading. I threw everything away and read it through.
After I've finished reading it, it's a bit,
“Your meal is dead”
In “don't be noisy and intrusive (angry),” the home also becomes empty, nothing, and empty in a bad sense.
There is a teaching that if you follow the sky, you will disobey the sky (Testimony Song).
If you hold on to the sky, you will be caught by the sky.
Try to find a gategat that isn't a literal gyatte.
If you do that, the living Heart Sutra will completely subside.
A Zen practitioner asked Yamaoka Tesshu to give a lecture on sutras.
Tesshu took that person to the sword dojo and showed them how they were practicing.
“This is my lecture, okay? You don't do it because you think there is truth only in letters.”

The person I met

This is Kawaguchi Hidetoshi. This is my humble answer to the question.

Until now, I have also dealt with the Heart Sutra in the following questions.

As the name suggests, the Heart Sutra is a sutra of wisdom that explains the heart of “Hannya Haramitsu.”

“Everything is empty.” That's it. I think the sky is nothing and infinity.” ・・

First, it's certainly true that everything is “empty.”

However, that “sky” is also an “sky.” This is a difficult place to understand, but please continue to have a strong interest in it and continue to learn.

And, secondly, “sky” means not “nothing” of “emptiness, absolute nothlessness,” and it simply means that it is not established by “entity/selfessness/self-image.”

Also, when “sky” means “nothing and infinity,” the contradiction is contained in the fact that “it is nothing and is infinite.”

“Nothing” is just “nothing,” and originally, there should be no room to “have” anything from “nothing,” and “nothing” makes it impossible to explain anything about phenomena and events in this world.

Therefore, “sky” does not mean “nothing” where there is nothing.

“Infinity” is also a subject matter of what is infinite, but for example, discussions about whether this universe or the world is finite or infinite can be rejected as “unrecorded,” and as something that is not useful for much discussion.

Also, even if “infinity” is assumed to be some kind of thing or thing as an entity that does not change forever, it means that there is no such thing or thing.

By all means, there are various interpretations of the Heart Sutra, but I would be happy if you could refer to the above for your understanding.
