Material things are not to be despised—without them there can be no manifestation in the material world.
Physical things have a life and value of their own which does not depend upon their price. To respect physical things and make a careful and scrupulous use of them is a part of the Yoga, for without that the mastery over matter cannot come.
….there is a consciousness in them, a life which is not the life and consciousness of man and animal which we know, but still secret and real. That is why we must have a respect for physical things and use them rightly, not misuse and waste, ill-treat or handle with a careless roughness. This feeling of all being conscious or alive comes when our own physical consciousness—and not the mind only—awakes out of its obscurity and becomes aware of the One in all things, the Divine everywhere.
