V. Sickness and Healing
How are experiences transformed in the soul into ability and wisdom? They are transformed by being taken in their immediate form into our sleep each night, into those spheres where the soul or the inner human being reside during the night. There the experiences which occur over a period of time are changed into essences. Any observer of life knows that if one wants to master and co-ordinate a series of experiences in a single sphere of activity it is necessary to transform these experiences in periods of sleep. For example, a thing is best learnt by heart by learning it, sleeping on it, learning it again, sleeping on it again. If one is not able to immerse the experiences in sleep in order for them to emerge as abilities or in the form of wisdom or art, then they will not be developed.
