As the surface of the heart is known by the imagination and thought, so the depth of the mind, which is the heart, is known by feeling.

• The difference between thought and imagination is that imagination is an automatic working of the mind. If the mind is fine there is a fine imagination; if the mind is gross there is a gross imagination; if there is a beautiful mentality, the imagination is beautiful.
• Thought is also imagination, but imagination held, controlled, and directed by will. Therefore when we say: "He is a thoughtful person", it means that this person does not think, speak, or act on impulse, but behind everything he does there is will-power which controls and directs the action of his mind.
