Then God said, “Let the earth bring forth grass, the herb [ that ] yields seed, [ and ] the fruit tree [ that ] yields fruit according to its kind, whose seed [ is ] in itself, on the earth”; and it was so.
Then God said, “Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, [ each ] according to its kind”; and it was so.
Then God said, “Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over [g]all the earth and over every creeping thing that creeps on the earth.” So God created man in His [ own ] image; in the image of God He created him; male and female He created them. Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that [h]moves on the earth.”
Let me first make this disclaimer; I no longer call myself a Christian! Though I no longer accept the moniker, I tend to borrow from the Christian Scriptures because they are those with which I am most familiar, being the ones I was raised with. I believe, as I did even when I claimed to be a Christian, that the passages above do not necessarily refer to anything but the 'everlasting covenant' ( Genesis 9:16, 17:7 ) that the Hebrew God made with Israel. Even so, the words, however 'lost in the translation' they may be, still convey a certain Universal Truth which stands today. This Truth is that, even according to these Scriptures, all Biology ultimately springs from the Womb of our Mother Earth. Humankind, on the other hand, being the Image of God ( unlike mere animals ( ? ), were not instructed to 'bring forth', only to 'Be fruitful and multiply'. To 'Be fruitful and multiply' carries with it less physicality then the command to 'bring forth'; the point being that Humankind need not 'bring forth' more Humans in order to 'procreate', but must simply 'Be fruitful and multiply', whether it be through art or some other form of magick ( creativity ).
In the passages above, one might note that the Hebrew perception of the Source of All has been given a male Persona; while the Source of All is neither male nor female, the Deities that most cultures worship as apart from themselves have been assigned either one gender or the other. One might well note here that, in doing so, Humanity has neatly made 'God' in their own image! As the case may be, however, the Source of All, be It simply Energy or the Master of the Universe, rather than being male or female, like Humanity, indeed everything in this Biology, is not divided into male & female, but is, as the Christian Scriptures also say, 'above all, and through all, and in [c]you all'.
Clearly though, biologically speaking, human beings are made for physical procreation. Without going into too much information, or detail, suffice it to say that the male & female sexual organs fit together like hand in glove, normally speaking, anyway; obviously, there are exceptions to this rule. As the case may be, though the act of sexual intercourse, when done correctly & at the right time, will most often result in a pregnancy, or physical procreation, this is not necessarily always the case. If no pregnancy is desired, but the act itself ( which I hear can be VERY pleasurable ) is, then either the pair must engage in sexual intercourse at ONLY certain times, or the male may encase his sexual organ in a special covering & the female can also do certain things to allay this concern.
When done correctly, again, the physical act of sexual intercourse may bear much fruit, not least of which is strengthening the bond, both spiritually & physically, between the two participating in the act. I cannot speak from experience, never having 'sired' a Child, but from all ( or most ) accounts, the Joy that springs from giving rise to a new Human Being is like nothing else on this physical plane! Though this act, or the resulting 'consequence', is termed 'procreation', one might well wonder why it's not just called 'creation', for in Essence, that's what it is.
The Essence of What we are, as spirit-beings having a physical experience, is More than Human. Being thus, as normally understood, the act of procreation IS merely physical. Considering the above Truth though, the question should be presented; 'since we are More than Human, not merely physical beings, MUST procreation be simply a physical act?' 'Is there such a thing a spiritual procreation?' I would venture to say, 'as above, so below', that 'yes', there most definitely is & it is far more important to the survival of the human race than the physical act! 'How does one spiritually procreate?', you may ask. Well, we've already covered this to some extent, but to put it plainly, spiritual procreation is as simple as the magickal act of letting your creativity flow.
The word 'procreate' or 'procreation' first appeared in the late 14th century, according to this article & means anything from 'the process of begetting offspring, generation and production of young' to 'bring forth'. 'As above, so below'; although, according to this fairly obvious definition, procreation is primarily a physical act, both the word & its definition seemed to be based largely upon the religious notion of a 'Creator'. Now, before someone blows a gasket; I'm by no means saying that there is NOT a Creator, or a Divine Intelligence Who put everything in motion! There very likely IS ( some would say, 'HAS to be!' ) a Master of the Universe, but on the other hand, there are those who say that it is the Universe itself that is Eternal. Again, still others would say that All is Energy ( which is true ) & that 'Intelligent' or not, Energy is Its own Generator!
Speaking of 'Energy'; anyone who has ever participated in the act of sexual intercourse knows how much Energy it takes. Not to get too graphic, but it takes a lot out of a person to employ his or her sexual organ. It IS ( or can be ) VERY pleasurable & although it is often over too quickly, there are ways which can be employed in order to prolong the gratification. Not having done much study myself in this area, I cannot say this with authority, but probably one of the best ways to reach this heightened 'gratification' ( 'ecstasy'? ) is of Eastern origins & has more to do with self-awareness than physicality, though physicality might seem to be, in modern times anyway, the predominant factor. The point is, the physical act itself, whether willfully or ignorantly, is overshadowed by the Higher Self. Although sexual intercourse is most often viewed as a predominately physical act & can indeed become very animalistic, it is, first & foremost, a spiritual exercise, one which is meant to bring balance to the Universe Itself.
It has been said that human beings are a microcosm of a much vaster macrocosm above. How true this statement is is not merely matter of conjecture or theory, it is a proven fact! The infinite wanders of the human body are, in some areas still, beyond comprehension, Yes, Science. with the help of Technology, has made great leaps in its study of the human anatomy, but it has yet to explain how the egg & sperm come together to 'create' a uniquely individual human being. It obviously does not just 'happen'; certain factors must occur ( not unlike the operation of the Universe ) in order for the new avatar to form correctly. That said, these factors, while obviously physical in manifestation, have their genesis in the spiritual realm.
In conclusion, then, while the generally accepted definition of the term 'procreation' refers to the physical act of producing offspring, it should be clear, if for no other reason than that the physical is simply a manifestation of the spiritual, that our Higher Self, again, whether consciously or not, guides our actions in the physical realm. In case any objection might present itself ( which I'd imagine it will ) obviously some people are unconscious of their Higher Self, which explains their animalistic behavior. In order to 'procreate' ( biologically speaking ), two people, one male & one female must magickally employ their collective Wills. Again, procreation may, by definition, be a primarily physical act, but in reality It all begins in the Spirit & in the Spirit It must remain, or it loses all meaning!
Namaste' & Blessed Be.
