"Because prudence tells me," she replied in a low, hurried voice, while her bosom heaved painfully, as though she were afraid to hear her own words; "because I see that the time is not yet come. Ah, Orion! you have not yet learnt to bridle the desires and cravings that burn within you; you have forgotten all too quickly what is past--what a mountain we had to cross before we succeeded in finding each other, before I--for I must say it, my dear one--before I could look you in the face without anger and aversion. A strange and mysterious ordering has brought it about; and you, too, have honestly done your best that everything should be changed, that what was white should now be black, that the chill north wind should turn to a hot southerly one.

And we are in Egypt--but the difference is a wide one when the rule is applied to love. How ever, all this is not from yourself. What you call prudence is the voice of that nun!" "It is the voice of reason," replied Paula softly. "The yearning of my heart had overpowered it, and I owe to my friend. . . ."
