 Above all, when you're doing yoga, your first relationship of being one is with the earth. To be in touch with the earth is important. A proper yogi means, if you can afford to do this, you must make a room with packed mud, with packed clay. On top of it, you put either a raw silk cloth or a cotton cloth, a raw cotton cloth, not sand-forised. And you do yoga on that for maximum impact, because this body, you might have forgotten, but the body knows that it's just a piece of the planet, always it knows. When you practice yoga, you want that to become a conscious and a living process for you, so that you experience yourself as one with the earth and which you're living. And I would say, eighty percent of your health depends on this, how much you're in tune with the earth. Eighty percent, eighty percent of your chronic ailments can just vanish simply because you kind of found a little rapport with the earth on which you're walking or sitting right now. So using rubber mats for yoga, I know there are Isha branded rubber mats. I look at it with great pain. But this is a sathguru, cotton mats get dirty, who's going to wash them in America, they don't know how to wash them, so we made the rubber mats. But this is sathguru, this is some special material which really insulates you. This is what I'm asking you, when I asked you the first question, are you here to experience life or dodge life? Unknowingly you're doing it in so many ways as to how to insulate yourself from life. If you, you might already know this, it's all over the place these days. Ninety percent of your body is bacteria, you know this? That means you're only ten percent occupant of this building, this construction you have, only ten percent is yours, ninety percent is microbes, they're constantly in and out, they're not just here. If you insulate this, that itself is sickness, that itself is sickness. If you insulate this from the rest of the world, you will become the potential of who you are is being lowered continuously. So if you're a, if you're a homebound person, that means every day you wake up in the same place, now largely, if it is so, it's best you use a cotton mat for your yoga, or a raw silk mat, not a plastic thing. That is for people who roll it up and go and do it in Central Park because they want everybody to see they're doing yoga. Today is my yoga day. Yesterday I came with my bicycle to Central Park, today I've come with my yoga mat. So that's a different kind of life. If you're doing proper yoga, how to yoga? You must be connected. Organic material so that there's no break.
