Lecture I
Such phenomena are already here. Man could perceive them if he were to pay attention. He would see that there are certain beings, for instance, who have developed themselves in this way too soon. Just as man, if he waits for the proper moment, will reach the Jupiter-state at the right time, so that he will then be able to direct his physical and etheric bodies, so there are beings, who have developed themselves in a certain respect prematurely, without waiting for the proper time. Such prematurely developed beings we possess in the birds, and especially in those which migrate every year. It is the so-called group-soul which is connected with the etheric body of each single bird. Just as the group-soul directs the regular migrations of the birds over the earth, so will man after he has developed Spirit-self or Manas command what we call the physical and etheric bodies; he will direct them and set them in motion. He will do this in a still higher sense from without, when he has evolved so far, that in addition he is also working at the transformation of his etheric or life-body.
