Now the conscious recognition of brotherhood requires a link; and that link awakens a feeling of brotherhood. For instance, in ordinary language when someone says, "This is my brother" it means only that the other is born of the same parents. There can also be a brotherhood of professions; there can also be a brotherhood in ideas, and a brotherhood of those born in one city; and to the extent that a person is conscious of the link that binds one with the other, so far will one realize brotherhood. If he does not feel conscious of that link, even if they are brothers, they will feel strangers. So that the strength of brotherhood does not lie in the claim, but in the consciousness of that link; not in the profession that brotherhood exists, but in the conscious recognition.
