Kailas

Kailas is considered a sacred place in four religions: Bön, Buddhism, Hinduism, Jainism.
According to Hinduism, Lord Shiva, the destroyer of evil and sorrow, resides at the summit of a legendary mountain named Kailāsa, where he sits in a state of perpetual meditation along with his wife Pārvatī.
According to Charles Allen, one description in the Vishnu Purana of the mountain states that its four faces are made of crystal, ruby, gold, and lapis lazuli. It is a pillar of the world and is located at the heart of six mountain ranges symbolizing a lotus.
The largest and most important rock-cut temple, Kailash Temple at Ellora, Maharashtra is named after Mount Kailash. Many of its sculptures and reliefs depict episodes relating to Lord Shiva and Maa Parvati, including Ravana's tale. (Ravana was a devotee of Lord Shiva. Ramayana does not document Ravana shaking the mountain.) Ravana's mother had fallen ill. As they were great Lord Shiva devotees, he had attempted to carry the temple on his back to bring it closer to his mother. Shiva, being stunned by his boldness, had blessed him with immortality as Ravana had passed Lord Shiva's test of devotion.

In Jainism, Kailash is also known as Mount Ashtapada and is the site where the first Jain Tirthankara, Rishabhadeva, attained Nirvana/moksa(liberation).[The authenticity of Mount Kailash being Mount Ashtapada is highly debated]

Tantric Buddhists believe that Mount Kailash is the home of the Buddha Demchok (also known as Demchog or Chakrasamvara), who represents supreme bliss.
There are numerous sites in the region associated with Guru Rinpoche (Padmasambhava), whose tantric practices in holy sites around Tibet are credited with finally establishing Buddhism as the main religion of the country in the 7th-8th century CE.
It is said that Milarepa (c. 1052-c. 1135 CE), champion of Tantric Buddhism, arrived in Tibet to challenge Naro Bön-chung, champion of the Bön religion of Tibet. The two magicians engaged in a terrifying sorcerers' battle, but neither was able to gain a decisive advantage. Finally, it was agreed that whoever could reach the summit of Kailash most rapidly would be the victor. While Naro Bön-chung sat on a magic drum and soared up the slope, Milarepa's followers were dumbfounded to see him sitting still and meditating. Yet when Naro Bön-chung was nearly at the top, Milarepa suddenly moved into action and overtook him by riding on the rays of the sun, thus winning the contest. He did, however, fling a handful of snow on to the top of a nearby mountain, since known as Bönri, bequeathing it to the Bönpo and thereby ensuring continued Bönpo connections with the region.
