Ancient kabbalah.

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.

The first kabbalistic book, known today. is the Sefer Yetzirah (Book of Creation) by the great patriarch Abraham. This book is the first book of axioms (mishnaot) including laws about connections between Hebrew letters and physical reality. The first axiom (mishna) is fundamentl law of the Creation: "22 letters and 10 sefirot the God is created the Creation". The spiritual and physical matters are made of 22 letters and ten sephirot.
The names of God and spiritual names have a direct relationship to divine and spiritual forces. The physical forces are a reflection and manifestation of the divine and spiritual forces. The physical forces and energies and also divine and spiritual names have a direct relationship with one.
Modern science knows that matter is nothing but an illusion and that everything in the universe is made out of energy. Everything in the universe is made from energy (physical forces). "Everything we call real is made of things that cannot be regarded as real.” ~ Niels Bohr. In reality, all things of physical reality are made up of 22 letters and 10 sefirot.
There are two parts of the Torah internal and external. The external part of the Torah is a set of social laws, etc. According to the Midrash, the internal part of the Torah is the blueprint for Creation and a set of divine and spiritual names, which have a direct relationship with divine and spiritual forces.
The book "Sefer Yazira" is introduction in the internal part of holy language. Algorithm of creation the world is based on Hebrew's letters, a ten sefirot and the five operations over spiritual letter combinations: legislate, select and divide, weight, attache and convert
The four Hebrew letters transliterated as YHVH is the name of God in the Torah. The four letters YHVH ( Yod Hey Vav Hah) are points to Yod - wisdom (names of G-d – divine forces). Hey - understanding i.e. calculation and weighing of wisdom (weighing of names of G-d and calculation of divine forces). Vav - spiritual building blocks created by wisdom and understanding. Hah - lower malchut (kingdom) - the border between spiritual and physical reality and place of transformation of divine and spiritual building blocks to physical building blocks and transformation of divine and spiritual matter to physical matter and matter of the universe.
