It is difficult at the first thought to say whether it is the impression of the external part of ourselves which forms the mind, or if it is the impression of the inner part which forms the body. In reality both do their work: body makes mind and mind makes body. The mind makes a stronger impression upon the body, and the body makes a clearer impression upon the mind. The thought of illness brings illness to the body; the thought of youth and beauty develops these qualities; at the same time cleanliness of body helps to bring purity to the mind; strength of body gives courage to the mind.

Mind upon Body

Every change in the muscles and features takes place under the influence of the mind. In other words the mind "paints" the picture of the body, its vehicle in life. Wrath, hatred, jealousy, prejudice, bitterness, and all evil thoughts work upon one's physical self even before manifesting themselves. In the muscles of the features, in his face, every person shows his follies, which can never be veiled from the eyes of the seer. So it is with love, kindness, appreciation, sympathy, and all good thoughts and feelings. All show in one's face and form, and give evidence of one's goodness against a thousand accusations.

Sin and virtue would have no effect upon a person if the mind did not take impressions; nor would good and evil thoughts work on the external body if impressions were erased from the mind immediately. The sages in the East have, therefore, mastered concentration, that by its help they might be able to wipe off all that is undesirable, since it is human to err. But one arrives at this power by collecting all the good one can in the mind, so that evil may be naturally repulsed. By constantly doing so one acquires mastery.
