There is no doubt that love and sex are the center of gravity of our lives. Yet humanity does not realize that love and sex are also the center of spiritual life, if we know how to live an upright sexual life.
"Observe that in any place of scripture where the male and female are not found united together, the Holy One is said not to dwell or be present with His blessing..." - Zohar
"...the controlling of the sex nature builds up a reservoir of strength, and it is this strength that opens the door to the Innermost." - M, The Dayspring of Youth
