 All dairies are also referred to as yantra. The word yantra actually means a form. Because a machine is a complex arrangement of forms, the word yantra also extends to a machine. We can walk, so we came up with a bicycle. Whether it's a phone or a bicycle or a car or a machine, a flying machine, computer, whatever you call it. They're all just enhancement of what we already can do. Because we have tools and machines, we are an enhanced life. People do not understand how fantastic a thing tool is. Suppose I ask you to unscrew this screw in this piece of furniture. You may lose all your ten fingers and a few teeth, but it won't come. If I give you a little screwdriver, done, isn't it? That's the power of a tool. So like this, very sophisticated forms were created to take you into spaces that you yourself would not be able to go. So these are machines in a completely different dimension.
