Humans must experience suffering in order to comprehend the importance of their existence.
-- Masaaki Hisakawa (Chapter 4)

Look at this leaf. When you’re standing close to it you can see every single detail of the leaf. You may think that it’s important to see things, like this leaf, up close but that is an incorrect notion because it is also important to view things from afar. That’s why it is necessary to look at all perspectives of an issue or of an object.
--The Unnamed Samurai (Chapter 5)

You haven’t realized it yet but your life is precious. I always say that people should not do something that has no purpose. Is there a purpose behind your actions? Of course there is a purpose behind your decision to step into this bamboo forest. That is why your life is not meaningless.
--The Unnamed Samurai (Chapter 5)

Doesn't it seem that it is always by chance that these things happen, or is it because of the generosity of a shared knowledge of suffering that allows for it?

Lets reflect the hopes of the nations under oppression, injustice and brutality. All they see is Unknown suffering Of an empty heart and soul and thus their suffering is unknown. We cannot do everything; but still we can do something. Lend a hand to support the suffering ones.

There is nothing to opinions, they
may be beautiful or ugly, smart or foolish, everyone can support them or
discard them. But the teachings, you’ve heard from me, are no opinion,
and their goal is not to explain the world to those who seek knowledge.
They have a different goal; their goal is salvation from suffering. This is
what Gotama teaches, nothing else.
