The Dhyanalinga is a Yogic temple located 30 km (19 mi) from Coimbatore, Tamil Nadu. The temple was consecrated on June 24, 1999 by Sadhguru Jaggi Vasudev, a yogi and mystic. The temple is consecrated using prana prathista and is dedicated for meditation. Silence is maintained inside the temple. Dhyana in the Sanskrit language, means meditation and linga means form. Dhyanalinga is claimed by the owners of the temple to be a powerful and unique energy form created from the distilled essence of yogic sciences and the first of its kind to be completed in over 2,000 years. A subterranean tank located 35 ft (10.7 m) below holds a lingam immersed in water. Followers claim that the lingam is made of solidified and 99.8% purified mercury. The mercury is said to have been solidified at room temperature. Mercury has a Freezing point of −38.83°C at atmospheric pressure, but ancient Indian alchemy claims to have techniques to do so. These methods are said to have been used by yogis to solidify the lingam at room temperature.[5] People can take a dip in this water before they go to the Dhyanalinga temple. A semi-circular brick vault covers this tank, the inner sides of which have murals in pure natural dyes with its theme depicting a Maha Kumbha Mela scene.
