In the ordinary waking condition of physical life, man has, as a rule, very little power or control over his will and its impulses. The will is very detached from daily life. Only consider how little of all you do from morning to evening is really the outcome of your own thinking, of your personal resolutions. When someone knocks at the door and you say “Come in!”, that cannot be called a decision of your own thinking and will. If you are hungry and seat yourself at a table, that cannot be called a decision made by the will, because it is occasioned by your circumstances, by the needs of your organism. Try to picture your daily life and you will find how little the will is directly influenced from the centre of your being.
Why is this the case? Occultism shows us that in respect of his will man actually sleeps by day, that is to say he is not in the real sense present in his will-impulses at all. We may evolve better and better concepts and ideas; or we may become more highly moral, more cultured individuals, but we can do nothing as regards the will. By cultivating better thoughts we can work indirectly upon the will but as far as life is concerned we can do nothing directly to it, for in the waking life of day, our will is influenced only in an indirect way, namely through sleep. When we are asleep we do not think; ideation passes over into a state of sleep. The will, however, awakes, permeates our organism from outside, and invigorates it. We feel strengthened in the morning because what has penetrated into our organism is of the nature of will.
