This state of consciousness is also experienced in the dream; for the dream is the reaction of man's experiences in his wakeful state. The most wonderful thing which man can study in the dream is that the dream has a language, and a true knowledge of dream experiences teaches one that every individual has a separate language of his dream peculiar to his own nature. The dream of the poet, the dream of the man who works with his hands, the dream of the king, the dream of the poor man, all are different. There are many differences and one cannot give the same interpretation of his dream to every person; one must first know who has dreamed it. It is not the dream which can be interpreted by itself, it is the person to whom the dream came that one must know; and the interpretation is according to his state of evolution, to his occupation, to his ambitions and desires, to his present, his past, and his future, and to his spiritual aspirations.
