He used the word Bible to show the difference between a dry old book and a living teaching you can feel now, so you choose life over dogma.
From the Discourses
Passages where Osho speaks to this question — each links to the complete discourse.
Beloved master, what is the point of calling your juicy discourses, the bible?
[These discourses were first given under the title, THE RAJNEESH BIBLE -- Ed.] The point is clear. The Bible of the Christians is not juicy. They have destroyed a beautiful word, "bible." It has become dead. I want to make it alive. I love the word, and I want to give it all the juice that is possible. The point is very simple: so people can see the dead BIBLE and the living Bible -- the BIBLE which is just dry bones and the BIBLE which has juice. Now the choice is theirs. Okay?
Osho, a question arises in my mind. Last night you said some things about the scriptures. It seemed to me that whatever you say could also be found in the scriptures. And what you are saying is itself gradually becoming a scripture. And what you say about the scriptures will apply verbatim to what you yourself have said as well. One who can see will see it here too; one who cannot see will not see it here either. And one who can see will also see it in the ancient scriptures, while the one who cannot see will not see it there either. Then there remains no purpose in criticizing them.
If this much becomes clear to us, then you will see I am not condemning scripture; I am stating the factual situation of scripture. And what you say is right: much of what I say will be found in the scriptures—not because it is there, but because you will have understood me. If my words have been understood by you, you will find them in the scriptures, because in scripture you will find only what your understanding is. Whatever your understanding is, that is what you will find—because we project our own understanding into scripture. Ordinarily we think that understanding comes out of scripture. It does not. We put our understanding into the scripture. That is why a thousand commentaries on the Gita are possible. If understanding came out of the Gita, how could there be a thousand commentaries? And if Krishna had a thousand meanings, then Krishna’s mind must…
Osho, sometimes I have the feeling that you are not quoting the bible correctly.
That's possible. I am not a scholar, and if sometimes it is correct, it is a miracle. It must be coincidence. I am not a Christian either. I am not concerned with what exactly is written in the book, I am more concerned with what happened to Jesus in his innermost core. It has happened to me too, sol know what it is. When I am saying anything, I am not saying it according to the Bible, but according to the Christ-consciousness. And if sometimes you find that I am saying something which is not in the Bible, then at least in your Bible you can add it. And it will be absolutely true. It is possible... because I am a drunkard. I speak out of my drunkenness. If you are listening from a scholarly standpoint, you may be worried, puzzled; and you will miss much. You will have to…
Question: OSHO, PLEASE DESCRIBE AN ORTHODOX RAJNEESHEE. I said to his father, "First let me be acquainted... what is the situation?" So the next morning, rather than his father bringing him to me, I went into his room and I said, "Hello, Jesus Christ." He said, "You said 'Jesus Christ!'" I said. "Yes." He said, "But nobody believes me -- not my father, not my mother, even my friends have left me. Since I became Jesus Christ I don't have any friends." I said, "You can rely upon me. I don't like freaks, but Jesus Christ.... It is a great idea! You come with me. Now we can talk, now we are in the same boat." He said, "What do you mean?" I said, "Just come. We are in the same boat; you will understand what I mean.
A friend has asked: Osho, according to your statements, all dharmashastras—the religious scriptures that express the ideas of Buddha, Mahavira, and so on—are useless. Then why shouldn’t the books through which your ideas are expressed also be considered useless? Why should a person not advance only through his own experience? What need is there to listen to you?
And in response there are Jain books that say the same: it is better to be crushed under a mad elephant’s feet than to take refuge in a Hindu Shiva temple. That is a great sin; death is better than that. I am against this mentality. This mentality has caused great harm. How could I be opposed to books, to ideas, to the experiences of those who have enriched life? But I am opposed to deadness, and to the insistence that whatever we are clinging to is the only truth. This is the sign of a violent mind. A nonviolent, loving heart does not make such insistences. It is always open to think and to inquire. Always impartial. I spoke to you about this the day before yesterday, so I will not go further into it now. Let me simply repeat: I am in favor of books; I am not…
