In fact, owing to the barrier which separates the sacred from the profane, a man cannot enter into intimate relations with sacred things except after ridding himself of all that is profane in him. He cannot lead a religious life of even a slight intensity unless he commences by withdrawing more or less completely from the temporal life. So the negative cult is in one sense a means in view of an end: it is a condition of access to the positive cult. It does not confine itself to protecting sacred beings from vulgar contact; it acts upon the worshipper himself and modifies his condition positively. The man who has submitted himself to its prescribed interdictions is not the same afterwards as he was before. Before, he was an ordinary being who, for this reason, had to keep at a distance from the religious forces. Afterwards, he is on a more equal footing with them; he has approached the sacred by the very act of leaving the profane; he has purified and sanctified himself by the very act of detaching himself from the base and trivial matters that debased his nature. So the negative rites confer efficient powers just as well as the positive ones; the first, like the second, can serve to elevate the religious tone of the individual. According to a very true remark which has been made, no one can engage in a religious ceremony of any importance without first submitting himself to a sort of preliminary initiation which introduces him progressively into the sacred world.[1049] Unctions, lustrations, benedictions or any essentially positive operation may be used for this purpose; but the same result may be attained by means of fasts and vigils or retreat and silence, that is to say, by ritual abstinences, which are nothing more than certain interdictions put into practice.
