Mercury Lingam

While searching for blogposts upon ujjain, I came across this piece of news:

The Siddha Ashram of Swami Nardanand Paramahansa have completed the construction of a 1500 kilogram Parad (Mercury) Shivalingam, which is the largest of its kind in the world . The Shivalingam and its temple are located at Siddha Ashram, Ujjain in central India.

It is believed that an opportunity to see, touch and worship this Parad Shivalingam is accredited to one's holy and good deeds done in the previous and present life.

Some google search, and I found that you can even buy a chotu version for personal usage. Here !
So you ask whats the freaking point. Well there is this :

How can mercury affect my health ?
The nervous system is very sensitive to all forms of mercury. Methylmercury and metallic mercury vapors are more harmful than other forms, because more mercury in these forms reaches the brain. Exposure to high levels of metallic, inorganic, or organic mercury can permanently damage the brain, kidneys, and developing fetus. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems.
Short-term exposure to high levels of metallic mercury vapors may cause effects including lung damage, nausea, vomiting, diarrhea, increases in blood pressure or heart rate, skin rashes, and eye irritation

More on it, here.
So when the world is working to reduce the dangers of mercury, we are installing a lingam, so devotees can pray, touch, kneel and heal.
