Thus it is only in one respect that the length of the human Ego's sojourn in the spiritual world between death and new birth depends upon the above-mentioned cosmic data. In another respect it will depend upon the stages of the evolution through which the human being passes in the spiritual world. After a time this very evolution brings the *I* of man into a spiritual condition where he no longer finds sufficiency in the inner experiences of the Spirit. He beings to long for that altered consciousness which is reflected in physical experience and derives satisfaction from this reflection. The re-entry of the human being into earthly life is an outcome of these two factors: the inner thirst of the soul for incarnation, and the cosmically given possibility of finding a suitable bodily nature. Two factors therefore have to work in conjunction. Hence in one instance incarnation may result even before the “thirst” has reached its full intensity, a well-adapted incarnation being within reach; while in another it may have to wait till the thirst has outlived its normal culmination, since at the proper time no opportunity to incarnate was given. In so far as it is due to the whole character and quality of his bodily constitution, a man's prevailing mood and attunement to life will also be the outcome of these conditions.
