Let the leg slip slowly down, and when it is nearly flat on the floor again, let go, so that it gives entirely and drops from its own weight. If it is perfectly free, there is a pleasant little spring from the impetus of dropping, which is more or less according to the healthful state of the body. The same motion must be repeated with the other leg. Every movement should be slower each day. It is well to repeat the movements of the legs for three times, trying each time to move more slowly, with the leg heavier than the time before. After this, lift the arm slowly from the shoulder, letting the hand hang over until it is perpendicular to the floor. Be careful to think the arm heavy, and the motive power in the shoulder. It helps to relax if you imagine your arm held to the shoulder by a single hair, and that if you move it with a force beyond the minimum needed to raise it, it will drop off entirely. To those who have little or no imagination this will seem ridiculous; to others who have more, and can direct it usefully, this and similar ways will be very helpful. After the arm is raised to a perpendicular position, let the force of gravity have it,--first the upper arm to the elbow, and then the forearm and hand, so that it falls by pieces. Follow the same motion with the other arm, and repeat this three times, trying to improve with each repetition. Next, the head must be moved slowly,--so slowly that it seems as though it hardly moved at all,--first rolled to the left, then back and to the right and back again; and this also can be repeated three times. After each of the above motions there should be two or three long, quiet breaths. To free the spine, sit up on the floor, and with heavy arms and legs, head dropped forward, let it go back slowly and easily, as if the vertebrae were beads on a string, and first one bead lay flat, then another and another, until the whole string rests on the floor, and the head falls back with its own weight. This should be practised over and over before the movement can be perfectly free; and it is well to begin on the bed, until you catch the idea and its true application. After, and sometimes before, the process of slow motions, rolling over loosely on one side should be practised,--remaining there until the weight all seems near the floor, and then giving way so that the force of gravity seems to "flop" it back (I use "flop" advisedly); so again resting on the other side. But one must go over by regular motions, raising the leg first heavily and letting it fall with its full weight over the other leg, so that the ankles are crossed. The arm on the same side must be raised as high as possible and dropped over the chest. Then the body can be rolled over, and carried as it were by the weight of the arm and leg. It must go over heavily and freely like a bag of loose bones, and it helps greatly to freedom to roll over and over in this way.
