your thoughts, and your reserve forces will rush out into activity and you will be a changed man in no time. HOW TO EXERCISE. In exercising aim at rhythm of motion. Let your movements be easy, regular, rhythmic and graceful. Take an interest in your work. Do pay attention. Put Will-Power and Mind into your work. Think of all it means. Do not fatigue yourself unduly. After exercise towelling or a spray-bath is advisable. Wet your towel, pass it over your body, rubbing thoroughly. Raise the towel and repeat. After exercise and towelling, you should be in a splendid glow. Be sure to keep the windows open when exercising. Fresh air is an absolute necessity. Never mind about cold and so forth. Remember the Positive Denial will fill you with Power of Resistance. Say "Cold cannot affect my body" and believe what you say. You can face anything in this way and remain untouched. BATHING AND LINEN. The student should bathe daily, using plenty of water, rubbing and cleaning the body from top to toe. I myself bathe very early in the morning, in all seasons, in cold water. Cold water stimulates circulation and is a wonderful tonic internally and externally. Warm water is soothing and relaxing in its effect. If you can bathe in the flowing water of a river, so much the better. Swimming is a wonderful bracer, besides being an enjoyment in itself. There is Prana in water and your body extracts this Prana from air, water and food. I cannot give you instructions as to different forms of bathing, as this is not a "doctor" book. As far as possible bathe twice a day, mornings and evenings; if not, once in the morning, using the towel at other times. Bathing is not merely pouring water on body but cleansing it out and out with water rubbing and scrubbing with hands and towels. Aim at perfect cleanliness. Cleanliness is Godliness and Health is Holiness. Then again while bathing if you let the water flow over your body and try to "appreciate the sensation" and dwell on the idea of Prana-absorption from water, you shall get double benefit. About linen--_Be neat_, for God's sake. I have seen orthodox people who bathe twice and wash their hands hundreds of times in the day, but whose clothes are sticky with dirt, sweat and oil. Whatever else it may mean, Religion does not mean squalor, offensive odours in body and clothes and general neglect of external clean linen and dirt. The Yogi is a man of supreme REFINEMENT. Read that word and understand all it means. The clothes you wear in day-time should not be worn at night. Be clean internally as well externally. Be clean. Be clean. Be clean, within as well as without. DRINKING WATER AND SWALLOWING AIR. Your body needs a reasonable supply of water and air. Water is used by nature in different ways. Form the habit of drinking pure water from 5 to 8 tumblers a day. Drink slowly and form a mental image of Prana-absorption from the water.
