Yantra
Yantra literally means loom, instrument or machine. In actual practice, a yantra is a symbolic representation of aspects of divinity, usually the Mother Goddess. It is an interlocking matrix of geometric figures, circles, triangles and floral patterns that form fractal patterns of elegance and beauty. Yantras function as revelatory symbols of cosmic truths. It is believed that mystical yantras reveal the inner basis of forms and shapes abounding in the universe. A Yantra is for the visual sense the same as a Mantra is for the auditive sense - they are both instruments used to induce a specific resonance. Practitioners oftgen use a Yantra and a Mantra at the same time, usually representing the same aspect of the Divine.
Though drawn in two dimensions, a yantra is supposed to represent a three-dimensional sacred object. Three-dimensional yantras are now becoming increasingly common.
Meditating with a Yantra effectively is not culturally dependent, so a person can use it even outside the spiritual school it originated from. What is required though is a keen awareness and sensitivity in order to be able to "tune in" and feel its specific resonance.
The cruciform symbol of the Christian Cross acts in the same way as a Yantra in inducing a specific spiritual energy in the space where it is present, when it is contemplated with a reverent attitude. It can be seen as a form of "sacred geometry."
