Sadhguru explores the science of lingas, and explains how Dhyanalinga, at the Isha Yoga Center, is a "meditation machine." Meditativeness on one level means, creating a distance between you and your physicality, or in other words, it is a simple journey from untruth to truth.

Transcript of the video:

Sadhguru: The word "linga" comes from the root word "linga." Linga means the form. Why we are referring it to as the form is – I think already it must have been on a video, hmm? All this is in the video, is it? Okay. Then why am I talking about it. Anyway these lingas or these energy forms or these ellipsoids can be created with various qualities for various purposes. There are some lingas created for health, some for well-being and prosperity, some for spiritual progress, some for meditativeness, like this various types of lingas can be created. Essentially they can be categorized as seven different ways. These seven can be further multiplied into many, many kinds. The uniqueness of Dhyanalinga is it has all the seven dimensions of it but essentially it is tweaked towards meditativeness without any instruction. If you simply sit in the sphere of Dhyanalinga you become meditative. How many of you been there? Have you been there? Okay. No instruction, simply go sit there for ten minutes you will become meditative by your own nature without any instruction.

If you simply sit in the sphere of Dhyanalinga you become meditative. Simply go sit there for ten minutes you will become meditative by your own nature without any instruction.

So this is a unique space that’s been created which does this. It is a mercury-based linga. Its base is solidified mercury. Solidified mercury means ­mercury is available in its liquid form. The uniqueness of mercury is that it is a substance of the highest density found on the planet. Its specific gravity is 13.93 which is almost fourteen times that of water. So in terms of weight, if one liter of water weighs one kilogram, one liter of mercury weighs close to fourteen kilos. So this is the only substance found on the planet with such density and it's in liquid form. A liquid is heavier than almost all the solids or every solid that you can find on the planet and it can be solidified. Normally modern chemistry does not believe it can be solidified unless you take it to minus thirty-two degree centigrade. But there is an Indian alchemy which is known as the ‘Rasa Vaidya’ through which we solidify mercury, at the room temperature. You can see this – those of you had been there, you have seen in the Theerthakund, but similar solidified mercury is at the base of the Dhyanalinga, also in the background of Linga Bhairavi – it is all made of solidified mercury. Because of its density, if you energize it once, it stays that way for an extremely long period of time. We say eternally because we are thinking in terms of ten, fifteen thousand years also it will remain that way. And if the right kind of situation is maintained it may remain that way for hundred thousand years. Hundred thousand years in human experience is quite eternal. Yes? Hundred thousand years is quite an eternal time in terms of human life span because we are thinking in terms of sixty–hundred years.

So the idea and the science and the technology behind this is that you create an energy form which will do something that you want to do for a long period of time. A form is also referred to as a yantra. Yantra means today a machine. A simple form is a yantra. As you mix these many forms and make it into a more complex thing, then it becomes a machine. Various forms put together is a larger machine, isn't it? So similarly a simple form you take and add many, many, many, many parts to it and it becomes a complex machine. So it is in a way like a meditation machine. You simply sit there you become meditative. This is the experience of thousands of people - they come there thinking they want to sit there for ten minutes – they sit there and they get up, it's two hours. They’re sitting right there because once you are meditative, your sense of time is just gone. Time rules you only because you are strongly physical. The more physical you are, the more difficult it is to pass time, please see this. Have you noticed this?

Truth is not something that you do. You move away from untruth you are truthful. It's just that simple. So Dhyanalinga is just a tool towards that.

If you are intellectually active, time passes off much more quickly. If you are beyond the intellect, time just disappears in your experience but if you are just physical, time doesn’t go. You fidget, tch, tch. Isn't it so? The more physical you are, the more time tortures you. Time torture is only for the physical. If you are not physical, time doesn’t torture you. To become meditative means to create distance between you and your physicality, not to give it up but to carry it loosely. If you carry it loosely you can use it the way you want, when you don’t want, you can drop it. If you get enmeshed in it everything that is the quality of the physical also torments you. All the limitations of the physical infect you and bother you through the life.

So meditativeness on one level just means that you are creating a distance between you and your physicality. Or in other words it is a simple journey from ‘Asatoma Satgamaya.’ What is not true to true. What is it that’s not true? What is not true is just this - you gathered this (Referring to the body), it's a fact. But now you believe this is you. This is not true, isn't it? So truth means you moved away from untruth. Truth is not some kind of a thing that you do. If you don’t lie you are truthful. You don’t have to do anything to be truthful, isn't it? If you have to lie, it's a very complex exercise. Yes or no? Hmm? You know it by experience. Don’t you? If you have to tell a lie, it's a very complex exercise. To be truthful what do you have to do? Nothing, even a idiot can be truthful. Yes or no? It’s very simple. You simply sit here you are truthful, isn't it? If you want to tell a lie, it takes a lot of complexity.

So truth is not something that you do. You move away from untruth you are truthful. It's just that simple. So Dhyanalinga is just a tool towards that.
