I tried to find Him on the Christian cross, but He was not there; I went to
the Temple of the Hindus and to the old pagodas, but I could not find a
trace of Him anywhere.
I searched on the mountains and in the valleys but neither in the heights
nor in the depths was I able to find Him. I went to the Caaba in Mecca, but
He was not there either.
I questioned the scholars and philosophers but He was beyond their
understanding.
I then looked into my heart and it was there where He dwelled that I saw
Him; He was nowhere else to be found.

This quote from Frank Herbert's Dune is a litany against fear from the Bene Gesserit. I find the litany quite a good way to deal with the unexpected things in life. People so easily succumb to fear, whereas the human mind can conquer a lot of issues encountered in life and the universe.

"I must not fear. Fear is the mind-killer. Fear is the little death that
brings total obliteration. I will face my fear. I will permit it to pass over
me and through me. And when it has gone past, I will turn the inner eye to see
it's path. Where the fear has gone there will be nothing. Only I will remain."

From Uzumaki Naruto (<span lang="ja">うずまきナルト</span>):

Uzumaki Naruto: "Iruka-sensei (うみのイルカ), why do people risk their lives
for others?"

Iruka-sensei: "When someone dies, they disappear. Their past and present,
along with their future. A lot of people die on missions and in wars,
surprisingly quickly and easily. Hayate (月光ハヤテ) was one of them. The
one who dies has his own dreams, but there are people who are treasured like
those dreams. Parents, siblings, friends, and lovers, people who are
important... They all believe in and help each other. People who were there
since birth took care of them... And those bonds grow even stronger as time
passes. It's not just a saying. It will be so for the ones who are
connected, because it is precious."
