Kailash Mansarovar Tour is the most important pilgrimage tour for Buddhists, Hindus, and Jains. Pilgrim believed circling Mt. Kailash on foot will wash your sin and brings good fortunes. This Tour is considered off-limits to climbers in deference to Buddhist and Hindu beliefs. It is the most significant peak in the world that has not seen any known climbing attempts. According to one description in the Vishnu Purana or epic, Mt. Kailash is the center of the world; its four faces are made of crystal, ruby, gold, and lapis lazuli. It is the pillar of the world; is the center of the world Mandala and is located at the heart of six mountain ranges symbolizing a lotus. The four rivers Indus, Brahmaputra, Sutlej (a major Indus tributary), and the Karnali (a major Ganges tributary) flowing from Kailash then flow to the four quarters of the world and divide the world into four regions. The mountain is located in a particularly remote and inhospitable area of the Tibetan Himalayas. A few modern amenities, such as benches, resting places, and refreshment kiosks, exist to aid the pilgrims in their devotions. According to all religions that revere the mountain, setting foot on its slopes is a dire sin. It is claimed that many people who ventured to defy the taboo have died in the process.
