odin comes from wodanaz, who comes from the pie root "-odr" which means "to howl (furiously), another name who comes from this root is rudra (a god of howling storms, hunting, and having a "third eye"). rudra is treated as a lesser emanation of shiva in the rig veda, because rudra is an aryan version of shiva and is associated with hunting animals unlike the friend of animals pashupati (shiva's oldest form, that is explicitly known as a deity of vegan dalits and forest animal herder tribes). the trimurti is a concept in hinduism in which the cosmic functions of creation, maintenance, and destruction are personified by the forms of brahma the creator, vishnu the maintainer or preserver and shiva the destroyer or transformer. these three deities have been called "the hindu triad" or the "great triple deity", shiva being the third god as odin/hermes/mercury is the trito/trismegistus/etc... shiva is god of death, god of ravens, dogs and vultures, lord of cremation grounds, god of madness and wisdom, his colors are grey and dark blue (or alternatively red and black) and he carries a spear and dances to wardrums. he is agreed to be a direct cognate to odin by pretty much anyone who studies indo-european religion. there are even buddhist variants of shiva like mahakala and acala, who has one eye on heaven and one on the earth, carries a sword in one hand and a noose in the other, thought to symbolize their power to bind evil and take souls (odin is the god of hanged men, was said to bind evil and unfetter good, and was psychopomp, snatcher of souls). i think its possible odin replaced tyr as the prime god of the germanic pantheon, as something similar happens in celtic myth between nodens and lugh (nodens loses a hand while battling the fomorians, and the tuatha will only accept a fully formed king with no imperfections, so they elect lugh as their new king).
