Excerpts from the book Mystic's Musings
Question: Are there other Lingas in the world or is it a science limited to Indian culture? You also say it's not a religious symbol. How so? And what about the science behind the making of the Dhyanalinga?
Sadhguru: The incredible thing is that there are Lingas all around the world. In Africa there are terra cotta Lingas used for occult purposes. In Greece there's a temple with a Linga below the ground known as the 'Navel of the Earth'. This is purely manipuraka ¹. Somebody showed me the picture and I immediately knew what type of people consecrated this Linga. It was definitely done by Indian yogis. Somebody went there five thousand years ago and consecrated the Linga for manipuraka, probably because the local king or chieftain wanted victory, prosperity and well-being. So they created an instrument towards that purpose. As most temples were funded by kings, they mostly were manipuraka in nature, but a few kings who looked beyond those things wanted Anahata ² Lingas - also called Atma Lingas. Usually these Atma Lingas are for love and devotion, for ultimate dissolution. Anahata is a very malleable kind of state, accessible to most people. There are occult Lingas which are muladhara Lingas, very base, gross, and powerful, used for occult purposes. Those types of Lingas you can find in certain parts of Assam and Karnataka. There are secret temples, usually very small and powerful in their occult capabilities, but generally most Lingas are manipuraka.
Right now, most of the Lingas in the country represent one or two chakras at the most. Generally only one, because the Linga is made powerful and intense with one chakra for a particular purpose and is consecrated by mantras. The Dhyanalinga, which is empowered with all the seven chakras, was consecrated by prana prathishta ³. Holding all the seven chakras together was the greatest challenge. If I had wanted to create seven separate Lingas for seven chakras, that would have been so much easier, but the impact would not have been the same. The Dhyanalinga is like having the energy body of the most evolved being sitting there, or you could say, the highest being, referred to as Shiva, his energy body.
Another thing is, probably for the first time anywhere in the world, the Dhyanalinga is cared for by both men and women. Nobody has allowed women to do this kind of work before, but today, fourteen days in a lunar month - towards the full moon - women take care of the Dhyanalinga. The next fourteen days - towards the new moon - men take care of it. I think that's a big gift for the society to be able to go beyond these traditions. Bramhacharinis are there at Dhyanalinga, doing everything that needs to be done.
If one wants to do spiritual sadhana, he can have the intimacy of sitting with a Guru, a live Master. That is the purpose with which the Dhyanalinga has been created. So people come, sit for a moment and go, that's fine, but those who want to do sadhana can have that kind of intimacy with that energy which is not normally available for people. It's very rare for people to have such an opportunity.
