With physical exercise too, moderation is advised. (You should be cautious, or not attempt it if you have a respiratory or heart condition. Check with your physician if in doubt, and don't overdo.) One of the most useful physical exercises is pranayama, or controlled breathing (actually a type of hatha yoga exercise). For this and any
other calesthentics or hatha yoga which you might choose to do a 'kitchen timer' is suggested (many of these aren't accurate for under three minutes, but are helpful for longer periods).

The main purpose of pranayama is to relax the body and mind. There are many kinds of pranayama, but a simple one called the 'four-fold breath' will suffice. This consists of four short quick inhallations, then four short quick exhallations; then repeat, continuing until the allotted time is used up. It will take about 1 1/2 seconds for the four
inhallations, and about 1 1/2 seconds for the four exhallations; or about 3 seconds for the complete in-out cycle ('rep' for repetition). There should be no strain of any kind during your pranayama. You will probably notice a slight dizziness, particularly at first, since the effect of pranayama is to hyperventilate. Try sitting back in a chair with
your eyes closed when you do your pranayama. Begin a minute a day for the first week and gradually increase up to about five minutes a day. If you do the pranayama befor your magical activity, it will help you to get 'into the mood'. It is also an excellent aid to relaxation and tension release. Pranayama should not be done during heavy air
pollution. Other exercises you might consider are hatha yoga, calesthentics, walking or jogging.
