A Yantra is a geometric design acting as a highly efficient tool for contemplation, concentration and meditation. Yantras carry spiritual significance, and point the user to higher levels of consciousness. The idea is that every shape emits a very specific frequency and energy pattern. When one focuses on a Yantra, his mind is atomatically “tuned in” by resonance into the specific form energy of that Yantra. The process of resonance is then maintained and amplified. The Yantra acts only as a “tune in” mechanism or a doorway. The subtle energy does not come from the Yantra itself, but from the macrocosm. Basically Yantras are secret keys for establishing resonance with the benefic energies of the macrocosm. A Vastu Dosh can be corrected through the changes in the rooms, through interiors of the house, by changing the placements, by using regulators or using some charged objects.
