Spirit and Matter
22. Matter is generally defined as being “that which makes an impression on our senses,” or “that which is impenetrable.” Are these definitions accurate?
“From your point of view they are accurate because you can only provide a definition according to what you know. Matter exists in states that are unfamiliar to you. It may be, for instance, so ethereal and subtle that it makes no impression on your senses. It is still matter, even though it would not be such for you.”
a) What definition can you give of matter?
“Matter is the link that bonds the spirit. It is the instrument that serves it and at the same time it carries out its action.” From this point of view, one could say that matter is the agent or intermediary through and upon which the spirit acts.
