Shri Yantra is highly revered in Vastu Shastra as it symbolizes wealth and blessings from Goddess Lakshmi. To benefit from its positive energies, it's best to place the Yantra in your home's puja room or sacred space, facing east or north. Before keeping it, cleanse the Yantra by soaking it in saltwater for a day and then washing it with clean water. Regular worship, especially on Fridays, enhances its effectiveness.
