The Extreme Attitude of love is a secret feeling of love. It is like this I Will love to death, with my inner thoughts never revealed; Let others know it by my death smoke
It
is no longer a deep love if you allow it to be revealed during your
lifetime. The extent of love is limitlessly long when you carry
through with your love till death. Even if the other person asks you,
"Isn't it this?" you answer them by, "such a thing has never entered my
head."
The above is an extract from the book Bushido: Way of the samurai which is based upon the book Hagakure by Tsunetomo Yamamoto.
My interpretation of this passage about love is that it is not the
words you speak but your actions that define your love, and to merely
tell someone you love them means nothing compared to the act of dying
for that person. To give yourself up for someone in love even if they
do not know it truly shows how much you love that person for you did it for them, and not because you would recieve something in return such as thier love for you.
