Do not weary on the path, you who are taking the first and easiest steps of the journey that shall one day lead you to the Masters! The path is indeed steep, and as one inspired writer said, it leads uphill all the way; but there are stages at which the traveller may pause and enjoy the prospect. I seem to have reached such a stage myself, and though I am always working now, yet I enjoy my work. The awful battle that some of us fought with the elemental beings is now over. The worst calamity that could have befallen mankind is happily averted. The labor of the present is light compared with the labor of _that_ struggle. If the world could realize what it owes to the Masters whom most men regard as myths! But such Teachers do not work for gratitude nor for reward. Follow you in their footsteps, for it is the only road that can lead mankind above the awful calamities that threatened recently to engulf mankind. (_I am not referring to a mere German victory._) It is wise to keep from the knowledge of men in general the great evolutionary facts which govern the life of the planet. A mind must be lifted above the small circle of everyday interests before it could endure such knowledge. You all use words without realizing their meaning. You talk of guardian angels; you talk of hell and purgatory, and of vicarious atonement, and of sacraments. Sacraments! I could tell you of a sacrament that is verily an eating of the body and a drinking of the blood of God; but I refrain lest you should tell the world, and if you should tell the world the evil forces of the world would destroy you. But I am coming now perilously near the things that may not be spoken, so I will wish you a good-night--a good-night indeed--and go back to my labors, in the rear of that being of light who passed along the battlefields this evening. _April 17._ LETTER XXVII INVISIBLE ENEMIES YOU may have wondered why the elemental beings that as I have told you precipitated the great war were so malicious at this time, why they hurled themselves upon mankind with such overwhelming force. There is no reason why you should not know something of these causes, having seen so much of their effects. The saying that man has made more material progress in the last hundred years than in the preceding two thousand, has become a mere newspaper commonplace. It is because he has not made a corresponding moral progress that the evil elemental beings, who fear for their rule in their own kingdom, _could_ come so near to succeeding in their attacks upon the human race.
