Vastu Pooja is performed to seek the blessings of Vastu Purusha, the deity associated with the principles of Vastu Shastra, which is an ancient Indian architectural science. The purpose of Vastu Pooja is to harmonize the energies of a space and promote well-being, prosperity, and positive vibrations within a home or building.

Place a picture or idol of Vastu Purusha at the center of the altar. You can also include other deities or yantras associated with Vastu, such as Lord Kuber (the deity of wealth) or Vastu Yantras. Arrange other necessary pooja items like flowers, incense sticks, lamps, fruits, and sweets.

Begin by invoking the presence of Vastu Purusha and offer prayers for the well-being and harmonious energies of the space. Chant mantras or recite Vastu Purusha Vandana, seeking the blessings and guidance of the deity.

Offer flowers, fruits, and sweets to Vastu Purusha as a gesture of reverence. Light the lamps and incense sticks to create a sacred atmosphere. You can also sprinkle holy water or rose water in the space, symbolically purifying it.

If you have Vastu Yantras, place them in the appropriate directions or areas according to Vastu principles. Yantras are geometric diagrams with specific energies associated with them, and their placement is believed to enhance the positive energies of the space.

Remember, the intention behind Vastu Pooja is to create positive vibrations and harmonize the energies of the space. Along with performing the pooja, it is also important to follow Vastu principles in the design and arrangement of the space, considering factors like direction, placement of furniture, and color schemes. Consulting with a Vastu expert or professional can provide detailed guidance for aligning your space with Vastu principles.
