Here are some beautiful quotes from Rav Kook. I cannot recall where I got them from, however I think they are probably from Rav Moshe Lichtman’s translation of R’ Simcha Raz’s book "An Angel among men".
"I write not because I have the strength to write, but because I do not have the strength to remain silent"
"Whoever said that my soul is torn, spoke well. It is certainly torn. We cannot imagine a person whose soul is not torn. Only an inanimate object can be whole. A human being however is filled with conflicting aspirations, and an inner war rages within him continuously. Man’s true mission to fuse the torn fragments of his soul by means of an all inclusive concepts, an idea whose magnitude and eminence encompasses everything else, bringing it to complete harmony"
"Just as poetry contains rules, so too, rules contain poetry"
