Apart from observing an auspicious date, the Grhapravesha ceremony is a vital aspect and it is compulsory before moving into a house, whether rented or owned. In Indian tradition, the Grhapravesha ceremony is regarded as second in importance to the Vasthu. Sastra says that all dwelling spaces are alive with unseen entities and prayers are necessary to purify the space from negative energy and to allow the flow of positive energy into the property. It is believed that unholy vibrations may have resided in the vacant space, which is why prayers are conducted asking the unseen forces to leave before new, protective energies are invited to occupy the space.
It is recommended that a priest perform the Grhapravesha ceremony because it involves several levels of cleansing. In Vedic tradition, the sacred rites are performed to bestow good health, wealth, peace and prosperity to the house owner.
