Man shows in his life traces of all the conditions through which the clay that makes his body has gone. There are atoms of his body which represent the mineral kingdom, the vegetable kingdom and the animal kingdom; all these are represented in him. Not only his body but his mind shows the reflection of all the kingdoms through which it has passed. For the mind is the medium between heaven and earth. Man experiences heaven when conscious of his soul; he experiences the earth when conscious of his body. Man experiences that plane which is between heaven and earth when he is conscious of his mind. Man shows by his stupidity the mineral kingdom which is in him, thick and hard; he shows by his pliability the vegetable kingdom, by his productive and creative faculties which bring forth the flowers and fruits of his life from his thoughts and deeds.
