There is a very general idea that Sex is a physical function only. It is almost universally taught that when the life of the body ceases, sex-life ceases with it. Even among metaphysicians, who believe in the continuity of life after death, the absurd doctrine is taught that Sex has no place or part in spiritual life, that "there is no marriage nor giving in marriage" after death. This idea has been a powerful deterrent in keeping the race from seeking the higher areas of spiritual consciousness. Lack of mere physical vitality has erroneously been estimated as evidence of spirituality. Chastity has unfortunately been counterfeited by mere physical restraint, resulting in a type of human being whom the healthy, normal person instinctively refuses to emulate, deferring as long as possible the attainment of that which has been presented to the mind as "spirituality." Let it be understood at the outset of this presentation of the problem of Sex that we state emphatically, that Sex is an eternal verity. Its spiritual function is not _less_ but infinitely _more_ than that which we glimpse on the physical plane of life-expression. Far from outgrowing what we know as human love, we add thereunto a million fold, refining, purifying and _intensifying_ the sex instinct until it bears a relationship to the average instance of sex-expression, analogous to that which the single-celled organism bears to intellectual man. If we will keep in mind the fact that Life in all its degrees of manifestation is like the ascending notes of the musical scale, we will be able to get a more comprehensive idea of the spiritual function of the sex-urge. We will realize that we can not mark a too distinctive separation between the various phases of life-manifestation. We imagine that the physical life is widely at variance with the mental, the psychical, or the spiritual, when as a matter of fact each blends into the other, when we rightly understand their place and purpose, as harmoniously as the notes of the musical scale blend into the grand compositions of the Masters. "As above so below, and as below so above," is a truism which we may safely take as our first maxim. Whatever we note as a fundamental principle of this external life which we cognize with our five senses (senses which merge so into the psychical that we know not always where the line demarks) has a permanent place in the Cosmos. Therefore we must conclude that a fact so universal as that of sex, and sex-attraction, must be grounded in something more stable, more permanent and enduring than the mere creation of physical forms.
