Let me ask you a question about the present of Zen

It means that Buddhism is not a way of thinking. You don't need to understand it, and if you try to understand it, you'll walk away.
Certainly speaking, in words, I'm living in the present.
Also, I'm sure they've never been separated from now since they were born. That's why there's no need to bother living in the present.

There are also functions for thinking and remembering. It's a tool. It's not true, but if you don't make good use of such features in your life, you can't live. What I'm thinking about and remembering is also a “now” fact. So you don't have to go out of your way to say Nikon.

As we value facts in our lives, we will be able to live meaningfully and freely by discerning, thinking, and thinking about the truth.

For example, let's say you're currently working on the task of making a schedule.
That work is current work.
I'm currently working on the task of imagining the future.
At that time, if you're impatient thinking about doing another task, such as “I have to dry my laundry quickly,” you haven't been able to concentrate on the “here and now” moment.
For example, the task of remembering the past and writing a memo is the work itself of the present.
Even if you get frustrated while writing a memo and say, “Oh, I went out to eat early, but it's bothersome,” the memo I should write won't go away.
Even if you're not in such a hurry, you can go eat quickly if you write down memos that you should write steadily and quietly.
Being impatient doesn't mean I can write memos fast. Rather, I lost time because I wanted to “eat fast,” and the meal went away.
At this time, I can only do what I can.
Give up on what you can't do now if you can't do it now, and if you do what you can do now to the extent you can, then it would be good to be satisfied that you passed now.
On the other hand, it wouldn't be good if you can't concentrate on what you need to do now and your thoughts are scattered all over delusional distractions about the past and the future.
A staircase that can only be climbed one step at a time. If you are progressing steadily, even one step at a time, you should be satisfied that you have passed. If your consciousness takes the lead and you think a hundred steps ahead, you won't think you've passed now and you'll be dissatisfied.
In that case, in the end, your mind is caught up in the future a hundred steps ahead and you are neglecting the present.

In Buddhism, they are called the two wheels of wisdom and mercy, and wisdom is to capture the present moment by moment and realize that impermanence, suffering, and selflessness exist. Mercy is wishing for happiness in all lives. But when I'm thinking about all life, I'm not watching a series of instantaneous births and deaths.
In other words, I can see a difference in direction where wisdom is physics and mercy is biology.
It's not superior or inferior. In Buddhism, it is really called a double wheel, and what they aim for is wisdom, enlightenment, and discovery only now. However, if you don't understand that the life called “I,” which aims for it, is supported by various things and mercy is applied to it, the life called “I” will not reach enlightenment. Also, after wisdom opens up and becomes enlightened, there is no worry, so no matter what you do normally, even if you don't bother to work hard, what you do will benefit other lives as it is.
The ascetic practice for enlightenment is to prepare an environment and schedule, participate in zazen meditation, and do your best. Thanks to life and the environment around us, we can begin experiments in physics.
In everyday life, we are helped in our relationships with various lives, and we also help ourselves. Even for life's work called “me,” which is growing plants rather than biology, I must first settle for “the here and now.” Furthermore, I think I am living “here and now” by making full use of my future plans and the learning and experiences I have accumulated in the past.
Incidentally, new businesses are also being created while receiving them “right here and now,” and those businesses have been piling up all the time.

Hello.

There is a shochu called “now” (jikon), but we read it as “nikon.” Nikon is the camera manufacturer, but it doesn't seem to have anything to do with Buddhism. Incidentally, the origin of Canon's company name seems to be Kannon. “Now” is used to mean “time that has passed away” and “this moment” will never come back, so cherish the present moment. Even though the camera captures the “now and now,” it doesn't matter...

Now, are memories and plans “the same thing” as the past and future?

Even if you remember something, it doesn't mean you're actually going back to the past (or going to the future) like a time machine and doing anything there. It's just “me here and now,” “remembering the past,” and “planning for the future,” and it's not the past or future “itself.” You're just doing it in your head, right? Even the moment I'm thinking about the past hasn't gone back to the past and is progressing now.
If you remember things from the past, do your best to complete “the here and now who remembers the past.” When it's time to eat, focus on the meal; when it's a game, focus on the game; when you remember, focus on what you remember; when you make a plan, you focus on planning, and so on.

Also, I wrote “When you think about the past, focus on it,” but if you get too caught up in the past or future, the present will be neglected.
For example, since I do calligraphy, I'll talk about it by comparing it to calligraphy, but in calligraphy, I write while thinking about the finished form and how to finish the parts that failed in the middle of writing in a well-balanced manner. But if you think too much about the finished form or think too much about the failure of the written part, it won't work. It's about concentrating on this line I'm writing now, one by one, while keeping in mind the perfect form and failure. I think this is the same and important for our lives. I think it's important to focus on the present based on past experiences and future plans.
