Even in that heaven-world, despair seized him, when he found that the invisible barrier withheld him from his beloved. On her side she seemed equally desirous to come to him, and held out her arms in vain longing. On his face and her face were looks of appealing love baffled by the impossibility of meeting heart to heart. Then a shadow grew up between them swiftly; the shadow menacing and dark of a yellow-skinned man, rather like a Chinese, from whose throat ran a stream of blood. Who this man was Montrose could not tell, even though he had recognised Alice in a different guise. And the enemy--Montrose felt that the wounded creature was an enemy--grew larger and larger until the blackness of which he was part blotted out the splendour of the girl. Blotted out also the atmosphere of colour and music and radiancy, until Montrose, sinking downward in the gloom, opened his physical eyes to find himself seated in the chair opposite Eberstein. Only a single moment had elapsed, for the journey had been as swift as that of Mahomet to the seventh heaven mounted on Al Borak, but he seemed to have been away for hours. The discrepancy was to Montrose impossible to reconcile, even though he grasped confusedly the fact that he had been--in the Fourth Dimension say--where there is no time. "You now know what Alice Enistor has to do with you," said Eberstein in a quiet impressive tone. "I don't in one way," faltered the still bewildered young man, "and yet I do in another. All I can be certain of is that she is mine." "Undoubtedly. She is yours and you are hers." "Then why could we not come together?" "The shadow of your sin came between and parted you." "My sin?" "That which you committed five thousand years ago," explained the doctor patiently. "Then, self-willed, self-centred, you would not wait the striking of the hour which would have made you one, and therefore, seeking to obtain your desire by force, you broke the Great Law. The Great Law broke you, as it breaks all who disobey. For many ages your soul and her soul have been asunder, but now in the fullness of time you meet again on this physical plane in new vestments of flesh. But your sin has not yet been expiated, and you cannot yet be one with her you love. The shadow stands between you twain and will stand until the debt is paid." "The shadow--the man?" stammered Montrose confusedly. "You owe him a life!" "But he is my enemy. I feel strongly that he is my enemy." "He was and is: it depends greatly upon you if he continues to be. If one obeys truly the Law of Love, one must not be angered even with one's enemy. What says the Blessed Son of the Most High God?" As if the words had been placed in his mouth, Montrose replied softly: "Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you and persecute you!" Eberstein bowed his stately head. "Such is the Law of Love."
