SHIV PARVATI AND MT. KAILASH
Lord Shiva is the representation of the Supreme Being and the third element in the Hindu Trinity. The other two members are Lord Brahma and Lord Vishnu. Lord Shiva is known as the creator, destroyer and preserver of the universe.

This cycle of destruction and recreation is always in a circle. Whenever evil tries to take prominence over good Lord Shiva dissolves the universe and starts all over again. Lord Shiva is known as the God of mercy and kindness. He protects his devotees from all evil that are always around us. He blesses his followers with grace, knowledge and peace. Here are the important symbols that depict Lord Shiva. Each of his depiction signifies a different aspect of his supreme being. The unclad body covered with ashes: this form of Lord Shiva depicts his otherworldly image. This image means that the complete universe gives forth from him. But lord Shiva’s presence is much higher than this physical phenomenon.

According to Hinduism, Shiva, the destroyer of evil and sorrow, resides at the summit of a legendary mountain named Kailāśā, where he sits in a state of perpetual meditation along with his wife Pārvatī, the daughter of Himalaya. Kubera, the god of wealth was also said to have his abode on or near the mountain.

This Kailāśā is regarded in many sects of Hinduism as paradise, the ultimate destination of souls and the spiritual center of the world.

Some traditions also aver that the mountain is Shiva's linga and Lake Manasarowar below is the yoni of His consort. According to one description in the Vishnu Purana, Mount 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 84,000 leagues high; is the center of the world mandala; and is located at the heart of six mountain ranges symbolizing a lotus. The four rivers flowing from Kailash then flow to the four quarters of the world and divide the world into four regions.
