"My Confession" is a book by Leo Tolstoy. It belongs to his works dedicated to the subject of religion. This book includes original illustrations of the story.

Here are some passages from this book:
"And I ceased to doubt, and became fully convinced that not all was true in the religion I had joined. Formerly I should have said that it was all false, but I could not say so now. The whole of the people possessed a knowledge of the truth, for otherwise they could not have lived. Moreover, that knowledge was accessible to me, for I had felt it and had lived by it. But I no longer doubted that there was also falsehood in it. And all that had previously repelled me now presented itself vividly before me. And though I saw that among the peasants there was a smaller admixture of the lies that repelled me than among the representatives of the Church, I still saw that in the people's belief also falsehood was mingled with the truth.

But where did the truth and where did the falsehood come from? Both the falsehood and the truth were contained in the so-called holy tradition and in the Scriptures. Both the falsehood and the truth had been handed down by what is called the Church.

And whether I liked or not, I was brought to the study and investigation of these writings and traditions - which till now I had been so afraid to investigate.

And I turned to the examination of that same theology which I had once rejected with such contempt as unnecessary. Formerly it seemed to me a series of unnecessary absurdities, when on all sides I was surrounded by manifestations of life which seemed to me clear and full of sense; now I should have been glad to throw away what would not enter a health head, but I had nowhere to turn to. On this teaching religious doctrine rests, or at least with it the only knowledge of the meaning of life that I have found is inseparably connected. However wild it may seem too my firm old mind, it was the only hope of salvation. It had to be carefully, attentively examined in order to understand it, and not even to understand it as I understand the propositions of science: I do not seek that, nor can I seek it, knowing the special character of religious knowledge. I shall not seek the explanation of everything. I know that the explanation of everything, like the commencement of everything, must be concealed in infinity. But I wish to understand in a way which will bring me to what is inevitably inexplicable. I wish to recognize anything that is inexplicable as being so not because the demands of my reason are wrong (they are right, and apart from them I can understand nothing), but because I recognize the limits of my intellect. I wish to understand in such a way that everything that is inexplicable shall present itself to me as being necessarily inexplicable, and not as being something I am under an arbitrary obligation to believe.

That there is truth in the teaching is to me indubitable, but it is also certain that there is falsehood in it, and I must find what is true and what is false, and must disentangle the one from the other. I am setting to work upon this task. What of falsehood I have found in the teaching and what I have found of truth, and to what conclusions I came, will form the following parts of this work, which if it be worth it and if anyone wants it, will probably some day be printed somewhere".
