This is Kawaguchi Hidetoshi. This is my humble answer to the question.
How are you after the surgery? I sincerely pray for your recovery. Please don't overdo it, don't be impatient, and take your time to nourish yourself.
That's right... it's also difficult to say that it's pretty easy to understand...
First, it's not about dying and becoming “nothing.” I've dealt with this a little bit in the questions and answers below.
Question “I want to enjoy waking up in the morning and have an unavoidable, fulfilling day”

Question “What is the meaning of life?”
http://hasunoha.jp/questions/300
As I proceeded to learn about “sky and fortune” in Buddhism, I was able to understand a little bit about the state of mental inheritance that does not die little by little and becomes “nothing,” and continues even after death. Of course, it's still a bit of understanding by an immature person who is still a bit savvy, but... I've also dealt with this a little bit in the question below.
Question “I think about death”

Also, regarding fear of death, we have answered the following questions so far.
Question “The meaning of life, I'm afraid of dying”
http://hasunoha.jp/questions/292
At the level of ultimate truth (Katsu Yoshitaka) that Buddhism thinks, there is no “life” and “death” as an entity, and as a secular level (secular), it comes down to understanding what is called “emptiness and luck,” where you think there are “life” and “death” for the time being, but... hmm... it's still difficult...
Anyway, that's right... it doesn't end with death; I think it's important to adjust the state of mind now by not doing evil deeds, and keeping the state of mind (inheritance) clean with good “relationships” such as Buddha relationships if possible, so that the inheritance of a better heart towards enlightenment will continue from now on, so that the inheritance of a better mind will continue from now on, leading to enlightenment. In other words, it comes down to “all kinds of Buddhism” as the basis of Buddhism, that is the basis of Buddhism.
