YANTRAS OR MYSTIC DIAGRAMSThe Sri yantra, the ancient Tiintric ritual drawing, in addition to the highly complicated geometrical properties possesses a deep and detailed cosmogonical and psychophysiological interpretation. Such a duality is the outcome of the basic tantric idea about the close relationship between microcosmic and macrocosmic processes.A yantra is a graphic and geometric representation of the Universal energy. Thoughts and words cannot exist in the spiritual dimension since they are a construct of the intellect and mind. Sacred geometry arises from this fact that many philosophical truths cannot be expressed with words. The world around us is filled with geometrical designs and shapes. Ancient cultures, including those of Greeks, Egyptians, Chinese, Mayans and Hindus, observed that certain geometric patterns are found recurring throughout nature -spirals, hexagons and concentric circles to name a few) - and believed them to be the building blocks of all creation in the universe. In Hindu Tantra, three kinds of external symbols are used to relate to and connect with the Universal energy.• A yantra depicting the energy in the form of geometric shapesThe word yantra is derived from the root verb yantr meaning to restrain or control. It can be understood as a machine or a device that controls human effort in performing a task by providing assistance. A mantra uses sound energy to bring about a balance between the mind and the body
