Why do we worship the linga of Lord Shiva?

Why do we worship the linga of Lord Shiva? When Britishers first came in India , they found something that was truly un-comprehensible to them, they got stunned and perplexed completely when they saw people of India had worshipped a god, who had 'elephant face' , people of India had worshipped 'phallus' '( lingaa)' .Then they snickered at Indians. When any individual failed to understand, she makes fun of it, Britishers did the same with us and our culture. Cause of their poor imagination they couldn't visualise the reason or may be someone didn't explain to them. why indians worship of these God.? If you really wants to know why Hindu worship these god's you have to read answer with your open mind. 'Shiva linga' is a form , a symbol of our origin. Form is tangible and objective, thought is intangible and subjective. "When 'linga' meets with 'yoni' we come in this universe, we born , we incarnate, it's a symbol, how we came in existence, how we originated." If linga and yoni doesn't meet we never born so we Hindu worship the form of our origination. One day a sculptor was given a rock and asked to carve an image of God. He tried to imagine a form that would best match with God. If he carved a plant, he would exclude animals and humans. If he carved an animal, he would exclude humans and plants. If he carved a human, he would exclude plants and animals. If he carved a male, he would exclude the female. If he carved a female, he would exclude all males. God, he believed, was the container of all forms. And the only way to create this container was by creating no form. Or maybe God is beyond all forms, but a form is needed to access even this idea. Overwhelmed by these thoughts, the sculptor left the stone as it was and bowed before it. This was the linga, the container of infinity, the form of the formless, the tangible that provokes insight into the intangible. Only humans with his good imagination can visualise this idea of nature. This idea is contained in the linga. an idea known as sat-chitta-ananda, which means tranquillity (ananda) that follows when the mind (chitta) discovers the truth of nature and of the human condition (sat) by purging itself of all memories and prejudice. The name given to God was Shiva, which means the pure one, purified of all forms. "Shiva means that which is transcendent. Shiva means God who cannot be contained by space or time, God who needs no form." Shiva is Hara, who is indifferent to form, while Vishnu is Hari, who is appreciative of form. Shiva is God who breaks free from all forms, having found all of them limited, hence he is the destroyer who is worshipped as the linga. har har mahadev!!
