The laws of the spiritual world, perceived in this way by clairvoyant vision, hold good unconditionally. That this is so is shown by an example which it has often been possible to observe. It is instructive to see how thoughts of hatred, or at least antipathy, take effect even if they are not conceived in full consciousness.
There are school-teachers of the type usually known as ‘strict’, who are unable to gain the affection of their pupils; in such cases of course, the thoughts of antipathy and hatred are formed half innocently. But when such a teacher dies it can be seen how these thoughts too — for they persist — are obstacles in the way of his good endeavours in the spiritual world.
After the teacher’s death it is not often that a child or young person realizes that his hatred ought to cease, but he nevertheless preserves the feeling of how the teacher tormented him. From such insights a great deal can be learnt about the mutual relationships between the living and the dead.
