Tyr was the son of Odin though in Myth 17 he is made out to be the son of the giant Hymir. Like Odin, he has many characteristics of the earlier Germanic war gods. Tyr was an Aesir god of war with the Vanir. The Æsir and Vanir correspond to the Vedic Asuras and Devas. He was the son of Odin and Freya whose hand was bitten off by the monstrous wolf Fenrir. The Germanic parallel to Shiva's Maheshvara Sutra is the secret wisdom encoded within the "runic alphabet." It is to know the secret of runes that Odin hangs on the Yggdrasil tree for nine nights by sacrificing himself to himself: Odin must sacrifice himself to his "true self." He must "reintegrate" with the primordial serpent power of the runes. In Viking lore the Sacred Tree Yggdrasil has at its base a coiled serpent by a pool and in its highest boughs an eagle of the released spirit.
Trees of Life and Knowledge are identified with Scythian Aryans or Sumerian Anunnaki - the Dragon God-Kings- instrumental in establishing the Chakra system of Hindu and Buddhist Tantra and Hebrew, Arabic and Greek Cabala whose magical systems, as we all know, contain a glyph called the Tree of Life. The Cabalistic Tree of Life is a genealogical chart of the Gods.
Lord Shiva is Lord of the Nagas who once upon a time ruled over much of ancient India. They supposedly descended from the four wives of Maharishi Kashayapa the son of Lord Brahma the creator. The four races were those of the Devas, the Daityas, the Garudas and the Nagas. The Nagas were said to have been born of the third wife of the Turtle god Kashyapa named Kadru.
The Nagas were sworn enemies of the Garudas. Even today the natural enmity between eagles and nagas or serpents still exists. Odin is the Vedic equivalent of Rudra/Shiva who was worshiped prior to the Aryan invasion (second millennium B.C.). Shiva is, in fact, the oldest continuly-worshiped god in the world, Rudra is associated with storms, and with the hunt. Even the gods are intimidated by his zest for war. He is lord of ghosts, known to prowl about graveyards. Lastly, Rudra is the father of the Maruts, "a serpentine horde of warriors which make parallels to Siva Rudra and Odin/Wotan fairly evident; Odin's (Indo-) Germanic Männerbunde are also associated with storms, war, and the "wild hunt." Odin is the spiritual leader of the Männerbunde; Rudra is the spiritual leader of the Maruts.
Tyr descends from Transylvanian Scythian Aryans - the Dragon God-Kings who introduced the magical system containing a glyph called the Tree of Life, a genealogical chart of the Gods. The Anglo Saxon name Tiyrhe gave rise to the name Tiwesdaeg, or Tuesday. Tuesday is associated with the planet Mars and shares that planet's symbol, . As Mars rules over Aries and Scorpio, these signs are also associated with Tuesday.
The boar is sacred to both Mars and to Artemis This link between the apple and the boar, and the boar and Mars and Artemis or the Moon is identical with the association between the Apple Tree of Eden as Lilith (of the Moon) and Samael the Serpent or Dragon who embraces her. Essentially the symbols of the Boar and the Dragon have become interchangeable.
The third form of the Hindu avatar, Vishnu was a boar, Varaha. When the demon Hiranyaksha stole the earth (personified as the goddess Bhudevi) he hid her in the primordial waters, Vishnu appeared as the boar to rescue her. Varaha slew the demon and retrieved the Earth from the ocean, lifting it on his tusks, and restored Bhudevi to her place in the universe. Varaha represents yajna (sacrifice), as the eternal upholder of the earth. His feet represent the Vedas (scriptures). His tusks represent sacrificial stakes. His teeth are offerings. His mouth is the altar with tongue of sacrificial fire. The hair on his head denotes the sacrificial grass. The eyes represent the day and the night. Thus, Varaha is the embodiment of the Supreme Being who brings order amidst chaos in the world by his sacrifice. The Chinese zodiac is unique in including the Boar as one of its 12 animals. I have researched why that's the case without any convincing answer so I came to the conclusion that if the Boar was an avatar that's reason enough!
