Lord Shiva, the Omnipresent -

Shiva is 'Shakti' or power; Shiva is the destroyer, the most powerful of the 3 Godheads of the Hindu Trinity. In temples, Shiva's shrines usually contain a 'lingam', a phallic symbol which represents the energies necessary for life on both the microcosmic and the macrocosmic levels; that is, the world in which we live and the world which constitutes the whole of the universe. The 'lingam' is placed in the center underneath the spire, where it symbolizes the navel of the earth.
Performing Abhishekams to Lord Shiva will help erase your past bad karmas from your karmic sheet. Lord Shiva is said to be very fond of Abhishekams. Abhishekam is the process of bathing the deity. There is a lot of importance attached to abishekam in poojas. It makes the ceremonies many times more effective. A priest may perform an abishekam by simply using holy water or perform elaborately with elements such milk, curds, honey, ghee, sugar, coconut water, holy ash, sandal paste and fruit juice, to overcome your every day problems. Especially effective on the FULL MOON! There are SHIVA temples everywhere --
