Shiva - The most powerful and fascinating deity in Hinduism, who represents death and dissolution. One of the godheads in the Hindu Trinity, and known by many names - Mahadeva, Pashupati, Nataraja, Vishwanath, Bhole Nath - Shiva is perhaps the most complex of Hindu deities. Hindus recognise this by putting his shrine in the temple separate from those of other deities and worshipping Shiva as a phallic symbol called the ‘Shiva Limgam’ in most temples.
Shiva as Lord of Dance (Nataraja) As a symbol, Shiva Nataraja is a brilliant invention. It combines in a single image Shiva's roles as creator, preserver, and destroyer of the universe and conveys the Indian conception of the never-ending cycle of time. The symbols in the art imply that, through belief in Shiva, devotees can achieve salvation.
Meditation is all-inclusive, it excludes nothing. It is not a narrowing down of the mind, it is an expansion of consciousness. Concentration is of the mind, meditation is of consciousness. Concentration is mind, meditation is no-mind. Concentration is a tension: you will be tired of it sooner or later. You cannot concentrate for a long time, it is effort. But one can be meditative twenty-four hours, because it is relaxation. - Osho
