Griha Prabesh Pujan (Housewarming Pooja) is a Hindu ritual performed when moving into a new home. The ceremony is conducted to invite positive energies and seek blessings from deities for peace, prosperity, and well-being in the new abode. It includes prayers, offerings, and lighting of the sacred fire (Hawan), along with rituals that cleanse the space and remove any negative influences. The pooja is typically performed with family and close friends to mark the auspicious beginning of a new chapter in life.
