THE TREE OF KNOWLEDGE AND THE TREE OF LIFE. Part 1

The concept of a Tree of Life is a widespread myth in the World's mythologies, related to the concept of Sacred Tree, and in religious and philosophical tradition.
The Tree of Knowledge and the Tree of Life, connecting to heaven and the underworld, and all forms of creation, are both forms of the World Tree or Cosmic tree, and are portrayed in various religions and philosophies as the same tree.
In Pre-Islamic Persian Mythology, the mythic Gaokerena World Tree is a large, sacred tree which bears all seeds. Ahri-Man (Destructive Spirit) created a frog to invade the tree and destroy it, aiming to prevent all trees from growing on the earth. As a reaction, God (Ahura Mazda) created 2 Kar Fish that always would stare at the frog to guard the Tree. Because Ahri-Man is responsible for all evil including death, while Ahura Mazda is responsible for all good (including life) the concept of World Tree in Persian mythology is very closely related to the concept of Tree of Life.
In Ancient Egyptians, the Tree of Life represented the hierarchical chain of events that brought every thing into existence. The spheres of the Tree demostrate the Order, Process, and Method of creation.
In the Ennead System of heliopolis, the First Couple, apart from Shu and tefnut (moisture and dryness) and Geb and Nuit (Earth and Sky), are Isis and Osiris. They were said to have emerged from the Acacia Tree of LusaaSet, which was considered the Tree of Life, referring to it as the "Tree in which Life and Death are enclosed."Acacia Trees contain a chemical compound associated with spiritual experiences. A much later Myth relates how Set killed Osiris, putting him in a coffin, and throwing it into the Nile, the coffin becoming embedded in the base of a Tamarisk Tree.
In Ancient Armenia, the Tree of Life was a religious symbol and was drawn on walls of fortresses and carved on the armor of Warriors. The branches of the Tree were equally divided on the Right and left sides of the stem, with each Branch having One Leaf, and One Leaf on the Apex of the Tree. Servants stood on Each Side of the Tree with one of their hands up as if they are taking care of the Tree.
In Chinese Mythology, a carving of a Tree of Life depicts a Phoenix and a Dragon; the Dragon representing immortality. A Taoist story tells of a Tree that produces a Peach every 3000 years. The one who eats the fruit receives immortality. An archaeological discovery in the 1990s was of a sacrificial Pit at San-xing-dui in Sichuan, China. Dating from about 1200 BC, it contained 3 bronze trees, one of them 4 meters high. At the base was a Dragon, and fruit hanging from the lower branches. At the top is a strange Bird-Like (Phoenix) creature with claws. Also found in Sichuan, from the late Han Dynasty (25-220 CE), is another Tree of Life. The Ceramic Base is guarded by a Horned Beast with Wings. The Leaves of the tree are Coins and People. At the apex is a Bird with Coins and the Sun.
In Christianity, the Tree of Life represents the state of humanity free from corruption before the fall. After appearing in Genesis 2:9 and 3:22-24 as one of the two forbidden trees, the Tree of Life reappear
in the Book of Revelation, and most predominantly in the Last Chapter (22) of that Book as a part of the New Garden of Paradise. In contrast to its appearance in the Book of Genesis, the Tree of Life is no longer forbidden, for those who do Christ's commandments "have right to the Tree of Life."(v.14). A similar statement appears in Revelation 2:7. The last chapter begins with a reference to the "Pure River of Water of Life" which proceeds "Out of the Throne of God."  The River seems to feed two Trees of Life, one "on either side of the River" which "bear 12 manner of fruits" and "the leaves of the Tree were for healing of the Nations." (v.1-2).
In Germanic Mythology, Trees played a prominent Role. The Tree of Life appears in Norse religion as Yggdrasil, the World Tree. It is an immense Mythical Ash Tree with extensive surrounding lore that is central in connecting the 9 Worlds in Norse Cosmology and is considered holy. The apples from the Ash Box belonging to the goddess Ydun, provide immortality to the gods.
The tree's common name, "ash," goes back to the Old English "aesc," while the generic name originated in Latin. Both words mean "spear" in their respective languages.  The leaves are opposite (rarely in whorls of 3), and mostly pinnately compound. The seeds, popularly known as "keys" or "helicopter seeds," are a type of fruit known as a samara. It is a winged dry fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. The shape of the fruit enables the Wind to carry the seed farther away than regular seeds from the parent tree.
The Ash Tree (European Ash) belongs to a species of Fraxinus, nature to most of Europe from Portugal to Russia, with the exception of Northern Scandinavia and Southern Iberia. It is also considered native in Southern Asia from Northern Turkey East of the Caucasus and Alborz Mountains. The Northern most location is in the Trond-Heim Sf-Jord Region of Norway. The species now is widely cultivated and reportedly naturalized in New Zea-Land, and in scattered places in the United States and Canada (Nova Scotia, New Brunswick, Quebec, Massachusetts, Connecticut, New York, New Jersey, Maryland, Ontario, Ohio, Kentucky, and British Columbia).
