Graha Pravesh is a puja or ceremony performed on the occasion of one’s first entry into a new house or while shifting to a new house. Once the house is ready and one gets a possession, the family moves in on an auspicious day that is determined by the astrological charts and decided by pandits.
Purity of panchang (almanac) and auspicious time (muhurat) must be considered during the Graha pravesh. 3 types of Graha Pravesh have been mentioned in our ancient scriptures:
Apoorva: First entry to newly constructed house on a newly selected land is called apurva (new) Graha pravesh.
Sapoorva: Entry into an already existing house after travelling abroad or migration elsewhere is called sapurva Graha pravesh.
Dwandwah: Entry into a house to after renovation or reconstruction subsequent to damage due to fire, flood or earthquake, is termed as dwandwah (old) Graha pravesh. For apurva Graha pravesh, the exact auspicious time need to be adhered to. For sapurva Graha pravesh or dwandwah Graha pravesh, the purity of the panchang should be given due consideration.
