One knows that something is true but still doubts. Why does one doubt the truth?
The usual answer, it is because one is foolish! (Laughter)
But the truth is that the physical mind is truly completely stupid! You can prove it very easily. It is constructed probably as a kind of control, and in order to make sure that things are done as they ought to be. I think that this is its normal work… But it has made it a habit to doubt everything.
I think I have already told you about the small experiment I made one day. I removed my control and left the control to the physical mind — it is the physical mind which doubts. So I made the following experiment: I went into a room, then came out of the room and closed the door. I had decided to close the door; and when I came to another room, this mind, the material mind, the physical mind, you see, said, “Are you sure you have locked the door?” Now, I did not control, you know… I said, “Very well, I obey it!” I went back to see. I observed that the door was closed. I came back. As soon as I couldn’t see the door any longer, it told me, “Have you verified properly?” So I went back again…. And this went on till I decided: “Come now, that’s enough, isn’t it? Closed or not, I am not going back any more to see!” This could have gone on the whole day. It is made like that. It stops being like that only when a higher mind, the rational mind tells it, “Keep quiet!” Otherwise it goes on indefinitely…. So, if by ill-luck you are centred there, in this mind, even the things you know higher up as quite true, even things of which you have a physical proof — like that of the closed door, it doubts, it will doubt, because it is made of doubt. It will always say, “Are you quite sure this is true?… Isn’t it an idea of yours?… You don’t suppose it is like that?” And it will go on until one teaches it to keep quiet and be silent.
