Sacred mountains are central to certain religions, and are usually the subjects of many legends. For many, the most symbolic aspect of a mountain is the peak because it is believed that it is closest to heaven or other religious realms. Many religions have traditions centered on sacred mountains, which either are or were considered holy (such as Mount Olympus in Greek mythology) or are related to famous events (like Mount Sinai in Judaism, Christianity and descendant religions or Mount Kailash in Hinduism). In some cases, the sacred mountain is purely mythical, like the Hara Berezaiti in Zoroastrianism. Mount Kailash is believed to be the abode of the deities Shiva and Parvati, and is considered sacred in four religions: Hinduism, Bon, Buddhism, and Jainism. Volcanoes, such as Mount Etna in Italy, were also considered sacred, Mount Etna being believed to have been the home of Vulcan, the Roman god of fire and the forge.

Poised above the surrounding landscape, set in a fluid realm of drifting clouds and flowing sky, its summit appears to float in another world, higher and more perfect than the one in which we dwell. Center: The view of the mountain as the center appears in its most comprehensive form as a central axis linking together the three levels of the cosmos – heaven, earth, and hell or underworld. As the link between heaven earth, and hell, it acts as a conduit of power, the place where sacred energies, both divine and demonic, spew into the world of human existence. Power: Many sacred mountains are revered as places of awesome power manifested in various ways – natural, supernatural, and even political. Deity or
