To those desiring the monastic life ( Elder Ephraim of Arizona )

Oh, how can I appraise the inconceivable riches of virginity! What tongue of clay is able to extol its glory beside our Christ! Virginity is equality with the angels. It is that which makes an earthly human similar to our Christ and our Panagia, for both of them were virgins. Before Adam and Eve sinned, they were virgins; only after the Fall did they have marital relations. That is, virginity was dictated first, whereas marriage is a result of the Fall. Consequently, whoever wishes to attain the virtue that Adam and Eve had when they were in Paradise must live in virginity and chastity. 

Virginity and chastity have great boldness before God. 
Therefore, sacrifice even your lives; just guard your virginity as the apple of your eye. But, in order to keep it, you must say the prayer constantly and make sure that you avoid occasions of sin; be especially careful with your eyes.
