The Yantra is an instrument created by the power of mantras. The mantras channelise energies of the Universe for various purposes. Every yantra is made by invoking these chants on a special paper. The paper has a set of numbers written on it in a grid. These are written by a special ink. The paper is energised by the chanting. It is touched by pics and holy objects. This is then folded and put into a silver casing.
