“Your silent thoughts are like the roots of a plant. They remain hidden in the dark recesses of the earth, but from them stems the whole plant--its life and form, its strength and beauty. From them and through them the plant lives and dies. So, too, your thoughts, although hidden, are your real, vital force.”
