Yantra is a Sanskrit word which means an “instrument” or “apparatus”. Yantras are constructed on the immutable laws of sacred geometry. Theses yantras representating Gods are based on specific geometrical designs and mathematical equations, and provides us a focusing point for concentration and meditation. In this way Yantra can be called a Talisman (“Tabij”), a window into the absolute, in other words helpful to attain union with God.
Yantras can be defined as visual mantras also. They have been used since the Vedic age to remove the malefic forces and to strengthen the positive powers. In sacred books lots of songs have been sung about the glory of mystic power of yantras. Yantras are always essentials to the worship of Gods just as oil is essential to oil lamps. By establishing a yantra at pooja place and worshiping it every day one can fulfill one’s aspirations and desired goals.
Yantras is beneficial in every field of our life, to attain success in profession, to acquire wealth, peace, good luck to win in the court cases, to ward of diseases and to progress in meditation. These Yantras are prepared by knowledgeable person under proper guidance. Yantras are generally drawn on metals such as Gold, silver,copper, Bhojpatras and sometimes on paper also.
