What is the best time to practice?

For people with busy schedules, the answer is whenever you can. A good time is early in the morning, around sunrise. Practice in the morning is best on an empty stomach, so that the energy of the body is not being dissipated by digesting breakfast. Have breakfast afterwards. Early evening is also a good time, however, since these practices generate energy, you should avoid exercising too close to bedtime. The optimal (but least convenient) time to practice energy development exercises begins about two hours before dawn, which is when the earth is the quietest and naturally occurring psychic disturbance is lowest.
