“It is simply the truth which has come to our aid. It is truth which has given us life. Affection is the greatest of human feelings because it is made of respect, of lucidity, and light. To understand the truth and make one's self equal to it is everything; and to love is the same thing as to know and to understand. Affection, which I call also compassion, because I see no difference between them, dominates everything by reason of its clear sight. It is a sentiment as immense as if it were mad, and yet it is wise, and of human things it is the only perfect one. There is no great sentiment which is not completely held on the arms of compassion.”

The Inferno (1917), Ch. XIV
Context: I wanted to know the secret of life. I had seen men, groups, deeds, faces. In the twilight I had seen the tremulous eyes of beings as deep as wells. I had seen the mouth that said in a burst of glory, "I am more sensitive than others." I had seen the struggle to love and make one's self understood, the refusal of two persons in conversation to give themselves to each other, the coming together of two lovers, the lovers with an infectious smile, who are lovers in name only, who bury themselves in kisses, who press wound to wound to cure themselves, between whom there is really no attachment, and who, in spite of their ecstasy deriving light from shadow, are strangers as much as the sun and the moon are strangers. I had heard those who could find no crumb of peace except in the confession of their shameful misery, and I had seen faces pale and red-eyed from crying. I wanted to grasp it all at the same time. All the truths taken together make only one truth. I had had to wait until that day to learn this simple thing. It was this truth of truths which I needed.
Not because of my love of mankind. It is not true that we love mankind. No one ever has loved, does love, or will love mankind. It was for myself, solely for myself, that I sought to attain the full truth, which is above emotion, above peace, even above life, like a sort of death. I wanted to derive guidance from it, a faith. I wanted to use it for my own good.

1980s
Context: The questioner says, how can the conditioned brain grasp the unlimited, which is beauty, love, and truth? What is the ground of compassion and intelligence, and can it come upon us — each one of us? Are you inviting compassion? Are you inviting intelligence? Are you inviting beauty, love, and truth? Are you trying to grasp it? I am asking you. Are you trying to grasp the quality of intelligence, compassion, the immense sense of beauty, the perfume of love and that truth which has no path to it? Is that what you are grasping — wanting to find out the ground upon which it dwells? Can the limited brain grasp this? You cannot possibly grasp it, hold it. You can do all kinds of meditation, fast, torture yourself, become terribly austere, having one suit, or one robe. All this has been done. The rich cannot come to the truth, neither the poor. Nor the people who have taken a vow of celibacy, of silence, of austerity. All that is determined by thought, put together sequentially by thought; it is all the cultivation of deliberate thought, of deliberate intent.

Hat matt nicht die Augen, um sich sie auszureißen und das Herz zum gleichen Zweck? Dabei ist es ja nicht so schlimm, das ist Übertreibung und Lüge, alles ist Übertreibung, nur die Sehnsucht ist wahr, die kann man nicht übertreiben. Aber selbst die Wahrheit der Sehnsucht ist nicht so sehr ihre Wahrheit, als vielmehr der Ausdruck der Lüge alles übrigen sonst. Es klingt verdreht, aber es ist so.
Auch ist es vielleicht nicht eigentlich Liebe wenn ich sage, daß Du mir das Liebste bist; Liebe ist, daß Du mir das Messer bist, mit dem ich in mir wühle.

In this love you are like a knife, with which I explore myself.

1960s, Freedom From The Known (1969)
Context: What can a human being do — what can you and I do — to create a completely different society? We are asking ourselves a very serious question. Is there anything to be done at all? What can we do? Will somebody tell us? People have told us. The so-called spiritual leaders, who are supposed to understand these things better than we do, have told us by trying to twist and mould us into a new pattern, and that hasn't led us very far; sophisticated and learned men have told us and that has led us no further. We have been told that all paths lead to truth — you have your path as a Hindu and someone else has his path as a Christian and another as a Muslim, and they all meet at the same door — which is, when you look at it, so obviously absurd. Truth has no path, and that is the beauty of truth, it is living. A dead thing has a path to it because it is static, but when you see that truth is something living, moving, which has no resting place, which is in no temple, mosque or church, which no religion, no teacher, no philosopher, nobody can lead you to — then you will also see that this living thing is what you actually are — your anger, your brutality, your violence, your despair, the agony and sorrow you live in. In the understanding of all this is the truth, and you can understand it only if you know how to look at those things in your life. And you cannot look through an ideology, through a screen of words, through hopes and fears.
