What should I do if I die in a terrorist attack...
It's fine.
You can't do anything when you die, so there's no need to worry about what to do.
Fear begins by creating something that isn't there.
Once your imagination expands, you will be unable to move due to fear.
The area where you live is probably an area where terrorist attacks occur frequently.
However, the probability of dying in a traffic accident is probably higher than the probability of dying from a terrorist attack.
And yet no one gets into a car or an airplane considering the probability of death.
There is a saying in Nichiren Shonin's words, “You should learn about death first, and then learn various things later.”
I interpret it as meaning that the present should be fully fulfilled because it is a limited life.
Don't worry, people will die one day.
Long or short, that's all.
So, wouldn't it be better to live in the “now” so that you don't have any regrets?
If you always live your life hard without regrets, no matter when you die, you won't regret it.
Even if you think about various things before that happens, the world you imagine and the reality you meet will surely be different in appearance and shape.
The time you're afraid of is also your limited precious time.
Please don't waste it.
