If the rhythm has been lost, it must be brought back with great wisdom, because a sudden effort to regain the rhythm may make one lose it still more. If the rhythm has gone too slow or too fast, by trying to bring it to its regular speed one may break the rhythm, and by breaking the rhythm one may break oneself. This should be a gradual process; it must be wisely done. If the rhythm has gone too fast, it must be brought gradually to its proper condition; if it is too slow, it must be gradually made quicker. It requires patience and strength to do it.
