The falling and the rising and the falling again are indications of an unending conflict within.
This is important because sometimes a person may feel that his failure or decline is a sign of something essentially wrong.
To fall is not a sign of failure but rather an indication that one is making progress, that something essential is alive within one, something that, if it is lacking, makes progress impossible and invites the Angel of Death.
