Sefer Yetzirah - Book of Creation

And how could appear this flaw? He could appear, according to the Torah, because of the fact that our first parents in Paradise tasted the Forbidden Fruit of the Tree of Knowledge of Good and Evil! I have acquired a knowledge of these dual relations, ie of good and evil! And they were sent to live on Earth, where the matter, and there are laws of the ambivalent attitude! But where we are now, above all, should apply? Of course, to the Book of Creation, whose author is the prophet Abraham! But there are some points directly to the nature of this duality? This, above all, seven double sign the Hebrew alphabet! Why do they double? Because change their sound from the presence alongside them point - Signs Dagesh, doubling pronounced us in accordance with which dagesha without changing their sound! What are the signs? Beth-Vet, Gimel-?, Dalet-?, Kav-Ruff, Pei-Fei, Decision-?, Tav-?. So we can see that in the modern Hebrew language, which previously were not allowed to use the bustle of our lives, now preserved only the sound of three out of seven of these signs! Well, and because even if they were seven, then where can we get eight? Eighth is the mystery of the Kabbalah of Judaism, which tells us that when life on Earth, Shekhinah as Feminine God, was hidden in the "dust" matter! So sign Sheen, as the first digit in the Name Shekhinah, also has the duality of his playing Shin-Shin, but that does not obey the rule above referred Dagesha! Thus, the alphabet Hebrew language was originally in itself has the ability to offset shortfalls in eight bodies, the duality of his eight double sign!
