The silence became unendurable. I felt that I must overcome my languor so far as to address him. I am not a nervous man, and I never knew before what Virgil meant when he wrote "adhoesit faucibus ora." At last I managed to stammer out a few words, asking the intruder who he was and what he wanted.
"Lieutenant Heatherstone," he answered, speaking slowly and gravely, "you have committed this day the foulest sacrilege and the greatest crime which it is possible for man to do. You have slain one of the thrice blessed and reverend ones, an arch adept of the first degree, an elder brother who has trod the higher path for more years than you have numbered months. You have cut him off at a time when his labours promised to reach a climax and when he was about to attain a height of occult knowledge which would have brought man one step nearer to his Creator. All this you have done without excuse, without provocation, at a time when he was pleading the cause of the helpless and distressed. Listen now to me, John Heatherstone.
"When first the occult sciences were pursued many thousands of years ago, it was found by the learned that the short tenure of human existence was too limited to allow a man to attain the loftiest heights of inner life. The inquirers of those days directed their energies in the first place, therefore, to the lengthening of their own days in order that they might have more scope for improvement.
"By their knowledge of the secret laws of Nature they were enabled to fortify their bodies against disease and old age. It only remained to protect themselves against the assaults of wicked and violent men who are ever ready to destroy what is wiser and nobler than themselves. There was no direct means by which this protection could be effected, but it was in some measure attained by arranging the occult forces in such a way that a terrible and unavoidable retribution should await the offender.
"It was irrevocably ordained by laws which cannot be reversed that any one who should shed the blood of a brother who had attained a certain degree of sanctity should be a doomed man. Those laws are extant to this day, John Heatherstone, and you have placed yourself in their power. King or emperor would be helpless before the forces which you have called into play. What hope, then, is there for you?
"In former days these laws acted so instantaneously that the slayer perished with his victim. It was judged afterwards that this prompt retribution prevented the offender from having time to realise the enormity of his offence.
"It was therefore ordained that in all such cases the retribution should be left in the hands of the _chelas_, or immediate disciples of the holy man, with power to extend or shorten it at their will, exacting it either at the time or at any future anniversary of the day when the crime was committed.
"Why punishment should come on those days only it does not concern you to know. Suffice it that you are the murderer of Ghoolab Shah, the thrice blessed, and that I am the senior of his three _chelas_ commissioned to avenge his death.
"It is no personal matter between us. Amid our studies we have no leisure or inclination for personal matters. It is an immutable law, and it is as impossible for us to relax it as it is for you to escape from it Sooner or later we shall come to you and claim your life in atonement for the one which you have taken.
"The same fate shall be meted out to the wretched soldier, Smith, who, though less guilty than yourself, has incurred the same penalty by raising his sacrilegious hand against the chosen of Buddha. If your life is prolonged, it is merely that you may have time to repent of your misdeed and to feel the full force of your punishment.
"And lest you should be tempted to cast it out of your mind and to forget it, our bell--our astral bell, the use of which is one of our occult secrets--shall ever remind you of what have been and what is to be. You shall hear it by day and you shall hear it by night, and it will be a sign to you that do what you may and go where you will, you can never shake yourself clear of the _chelas_ of Ghoolab Shah.
