In the modern world, the sacred knowledge about the holy language remains hidden for understanding. In fact, we have known holy language for thousands of years. It’s one of the greatest mysteries that comes to us from Adam, Abraham and the Oral Torah. Adam, the first man, knew the holy language and transferred it to Noah, Abraham, Isaac and Jacob through Methuselah and Shem. Adam transferred the knowledge about the holy tongue to Hanoch and Methuselah. They were the first to teach Noah, who in turn taught his own students.
Early kabbalah addresses the unique properties of Hebrew in order to reveal sacred information about Hebrew letters and divine and spiritual names and their quantitative and logical evaluations. From 22 Hebrew letters and a ten sefirot God made up divine and spiritual names and the Torah. From them He made up spiritual matter (creation). Everything in creation is according to the letter combinations and 10 sephirot.
The sefirot are 10 emanations, or illuminations of God's infinite light as it manifests in creation. The physical world is a reflection and manifestation of the spiritual realm. The physical forces are a reflection and manifestation of the divine and spiritual forces. Everything that happens in the spiritual world takes place through the medium of the Sefirot. The names of G-d and spiritual names have a direct relationship with divine and spiritual forces and spiritual and physical matter.
In the Sefer Yetzirah, the letters of the alphabet are described as the stones of foundation of the universe. Letters and divine and spiritual names represent self all matter. Them are patterns of building blocks of creation. Holy texts are models of constructions of the creation. "The ten sefirot and the 22 Hebrew letters produced the material world, them are the formative powers of all existing and all physical reality."
Everything is connected and interdependent. Each letter or divine and spiritual name content diverse information about physical phenomena in our world and unique data about different aspects of our lives. The spiritual letter combinations of the Torah reflect diverse aspects of wisdom and spiritual knowledge.
Divine and spiritual names of the Torah are primary letter combinations (forces). From them, God produced secondary forces and spiritual names. The Hebrew letters or divine and spiritual names are roots of spiritual world; secondary names are branch of spiritual world. Physical reality was created by secondary forces and secondary names that reflect different aspects and properties of the physical world.

In Hebrew, generative recursive rules such as miluy which allow us from letter or letter combination to produce their derivatives which is called G-combinations which disclose reflect deep internal meaning of primary letter or letter combination. Because any lexical element of Hebrew text is founded by letter or letter combination we can to create for him G-combination by using generative recursive rules based on Hebrew alphabet or alphabets. Such rules may be applied repeatedly to generate an indefinite number of G-combinations for each lexical element. In this case, any G-combination is detailed descriptions of internal meaning of lexical element. By using these unique and miracle properties of Hebrew language, come to us from early kabbalah, we can calculate of natural gematrias by three stages:
a) the first step, calculation of G- combinations of lexical element by using operation n-miluim ;
b) the second step, calculation of ordinary natural gematrias for each G-combination of lexical element;
c) the third step, selection of natural gematrias from a set of ordinary natural gematrias by criteria: e.g. if two different components of ordinary natural gematria are same, then such gematria is natural gematria.
Natural gematrias unlike ordinary natural gematrias are numerical descriptions of G-combinations according to some criteria. Not all ordinary natural gematrias are natural gematrias. The quantitative and logical evaluation of any G-combination is vector. Ordinary natural gematria is ordinary vector, while natural gematria is vector whose components are defined by some rule/s.E.g. if (x,y,z) is the ordinary natural gematria and x=y, then (x,y,z) is natural gematria.
Gematria is a system of assigning numerical value to a word or phrase. G-combinations are someone that discloses internal meaning of lexical elements. Sacred mathematic use natural gematrias such as gematrical vectors and their derivatives such as functions, series, matrices, clusters, constructions and compositions. These mathematical objects related to music, sounds, vibrations and ratios of nature. These mathematical objects constitute the unifying concepts necessary for understanding universal music and universal music harmony.
