“To Initiated Adepts throughout the whole world … He is, as said, the “Nameless One” who has so many names, and yet whose names and whose very nature are unknown. He is the “Initiator,” called the “GREAT SACRIFICE.” For, sitting at the threshold of LIGHT, he looks into it from within the circle of Darkness, which he will not cross; nor will he quit his post till the last day of this life-cycle. Why does the solitary Watcher remain at his self-chosen post? Why does he sit by the fountain of primeval Wisdom, of which he drinks no longer, as he has naught to learn which he does not know – aye, neither on this Earth, nor in its heaven? Because the lonely, sore-footed pilgrims on their way back to their home are never sure to the last moment of not losing their way in this limitless desert of illusion and matter called Earth-Life. Because he would fain show the way to that region of freedom and light, from which he is a voluntary exile himself, to every prisoner who has succeeded in liberating himself from the bonds of flesh and illusion. Because, in short, he has sacrificed himself for the sake of mankind, though but a few Elect may profit by the GREAT SACRIFICE.”
