Pigs and fishes are the least intelligent of all animals and therefore the most difficult to influence. The force of inner truth must grow great indeed before its influence can extend to such creatures. In dealing with persons as intractable and as difficult to influence as a pig or a fish, the whole secret of success depends on finding the right way of approach. One must first rid oneself of all prejudice and, so to speak, let the psyche of the other person act on one without restraint. Then one will establish contact with him, understand and gain power over him. When a door has thus been opened, the force of one's personality will influence him. If in this way one finds no obstacles insurmountable, one can undertake even the most dangerous things, such as crossing the great water, and succeed. But it is important to understand upon what the force inner truth depends. This force is not identical with simple intimacy or a secret bond. Close ties may exist also among thieves; it is true that such a bond acts as a force but, since it is not invincible, it does not bring good fortune. All association on the basis of common interests holds only up to a certain point. Where the community of interest ceases, the holding together ceases also, and the closest friendship often changes into hate. Only when the bond is based on what is right, on steadfastness, will it remain so firm that it triumphs over everything.
