Thank you for providing me with another point of view as to why the Master would say this. According to your last quote of the Tarot and Kabbalah book, it sounds as though the Master is viewing it as a violation of the common cosmic trogoautoegocratic law.
One has to wonder why Master Moshe did not speak of it in Leviticus 18. I have yet to discover any other scripture that covers the subject either. It is spoken of in the Talmud, but I'm not certain that is a wholly reliable work. I suppose we must consider that the Bible may not be a wholly reliable work either, considering the adulteration that it has undergone over the years. I guess none of us can really be sure of any written work, including the Master Samael's. The urge of people to put their own egoic spin on things is just to strong in humanity. I suppose the only thing we can do is rely wholly on our Innermost to guide us.
To me it seems quite infrasexual to say that sex without orgasm would corrupt the nature of the child. I definitely see how the practice of animal sex could corrupt the nature of the child, but not what is taught here. I don't see how something so pure could be a corruption to anything. Although, one must consider, as the Master says, the bad in the good and the good in the bad. It is certainly another one of those issues that aren't really clear and to navigate is like trying to cross the edge of a razor without falling.
It is clear that the Master Samael Aun Weor is the foremost authority of occult wisdom in modern times and we must respect and consider that. As a Master he also stated,
"do not follow me, I am just a sign post. Find your own path."
The Master also stated,
"...facts are facts and when faced with the facts we have to surrender."
So it clear that it is our duty as seekers of our own path to seek out the facts and test them against our own intuition. Begging and praying to our Divine Mother for guidance.
Another factor is that I remember reading the Master stating that the soul, while the fetus is being gestated, can come and go as it pleases. Leaving the womb at will.
The soul is not a prisoner, however, for it can enter and leave the maternal womb and its body at will.

Once again, I am grateful for the efforts being put forth here to help those who may encounter confusion during their work. There are so many dangers in this path and it is good to consider the views of others who do this work also. Of course, experience is the path to Gnosis, so it is important to keep that in mind. That nobody can tell you the perfect will of your own personal Father.
