It is in the sacred books of India that we find the surest and most plentiful traces of this cosmogony or of this revelation. Less than a century ago, men were almost wholly unaware of the existence of these sacred books. Their interpreters have taken two different paths. On the one hand, scholars whom we may describe as official have supplied translations of a certain number of texts, which might also be called official, texts which they do not always understand and which their readers understand even less. On the other hand, initiates, genuine or pretended, with the assistance of adepts of an occult fraternity, have suggested a new and more impressive interpretation of these same texts or of others still more secret. They still, rightly or wrongly, inspire a certain distrust. We are obliged to admit the authenticity and the antiquity of certain traditions, of certain primitive and essential writings, though it is impossible to assign an approximate date to them, so completely are they merged in the mists of the prehistoric ages. But they are almost incomprehensible without keys and commentaries; and it is here that our doubts and hesitations begin. A large number of those commentaries are likewise very ancient and in their turn need keys; others appear to be more recent; lastly, others seem to be contemporary; and it is often difficult to draw a dividing line between that which may well exist in the original and that which the interpreters believe to exist in the original or which they more or less deliberately add to it. Now the most striking, the most impressive and in any case the most lucid part of the doctrine is often contained in the commentaries. Next, as I have observed, comes the question of the keys, which is intimately connected with the foregoing. These keys are more or less workable and command more or less respect; sometimes they seem fanciful or arbitrary; they are delivered only with curious precautions, singly and grudgingly; and they are apt to unlock several superimposed meanings. And all this is accompanied by fantastic reticences, by so-called dangerous or terrible secrets, withheld at the decisive moment, and by revelations which, it is contended, cannot be communicated until many centuries have elapsed. Doors through which we were about to pass are slammed in our faces just as we were at last catching a glimpse of a long-promised horizon; and behind each of them hides a supreme initiate, a still living master, the sacred guardian of the ultimate mysteries, who knows all things, but can or will say nothing.
