One must learn to speak the truth.
This may sound strange to you. It may seem to you that it is enough to wish or to decide to do so.
But it isn’t.
People comparatively rarely tell a deliberate lie. In most cases they actually think they speak the truth. Yet they lie all the time—both when they wish to lie and when they wish to speak the truth. They lie all the time—both to themselves and to others.
Therefore nobody ever understands either himself or anyone else.
Think about it—could there be such discord, such deep misunderstanding, such animosity and hatred towards the views and opinions of others, if people were able to understand one another?
Of course not.
So people cannot understand because they cannot help lying.
To speak the truth is the most difficult thing in the world; and one must study a great deal and for a long time in order to be able to speak the truth. —The wish alone is not enough.
To speak the truth one must know what the truth is and a lie is, and first of all in oneself.
And this nobody wants to know.
