Lecture II
The power of investigating one's own life, or that of another, in the spiritual world, can be acquired—curiously enough—through the forces left over in the etheric body from our learning to walk. Practical clairvoyance shows us that these forces, when really developed, have certain advantages over the clairvoyant forces developed for the purpose of looking back into former lives. I want you to pay particular attention to this difference between them, for it may throw light in many respects on various things. There is no way in which a dangerous clairvoyance is more easily developed than by using the forces which exist in present-day man for developing the organs of speech, and which, if kept back, enable him to see into his former earth-lives; for they are mostly connected with the lower instincts and passions in man's nature. In no other way is one brought so near to Lucifer and Ahriman as by developing these forces, for although they certainly lead one to the height of being able to look back into one's own and other people's past lives, yet they lead to the powers of illusion; and if not rightly developed the clairvoyant may, under their influence, fall morally low, rather than rise to the heights. Thus these forces are among the most dangerous of all, and should only be developed if at the same time the teacher is determined to develop the purest morality in his pupils. For this reason an experienced teacher will not easily allow himself to be persuaded systematically to develop the forces which enable a man to see former incarnations. It is just as rare to find the forces developed objectively, in the right way, i.e. by only using the speech-forces for this purpose, as it is common to find a certain lower clairvoyance which can see into the spiritual worlds and give descriptions of certain spiritual regions. That is why other means are generally used when it is desired to lead persons to see their earlier incarnations, and here we reach an interesting point—showing how necessary it is to pay attention to things which are generally disregarded. It is but seldom that anyone is able through his spiritual teaching to look back at his earlier earth-lives by developing the speech-forces only; that is a very rare occurrence, yet there are many persons at the present time who can do so. This has generally been reached by other means, one of which may strike one as strange, but it rests upon a profound truth. Suppose that a man is well advanced in years; it would need too much of an effort, and perhaps lead to too much temptation, were he to look back karmically at his former lives by developing the speech-forces. Therefore the spiritual forces have recourse to another means, which many suppose to be merely accidental. He may meet a man who calls him by a special name, or mentions a certain time, or a certain people. This works externally upon his soul in such a way that as a result he may develop the necessary forces to serve as a support for clairvoyance etc. will then notice that the name he was called by, or the words mentioned, will, without any knowledge of this on the part of the speaker, lead to a retrospective view of his past lives. This is a case of outer means being resorted to. The man in question hears a name or an era or a nation mentioned, and is thereby stimulated from outside, as it were, to see his former earth incarnations. Such external stimuli are sometimes of' great importance to a clairvoyant observation of the world. One has what seems to be an entirely accidental experience, but from this rays forth a stimulus for clairvoyant forces which one otherwise possesses only in rudimentary form.
