Once the construction of a new home is complete, the day you enter the house to inhabit it should be an auspicious one. The best time for entry into a newly constructed house is when the sun is in the Uttarayan position (summer solstice). The night before the griha pravesh, there are a few ceremonies to be completed. They are sthana shudhi (purification), vastu bali and panchashira sthapanam.
The Griha pravesh ceremony starts before sunrise. Starting this ceremony with Ganapati homa will remove any obstacles. After the homa keep the homa fire burning. The house should be elaborately decorated for the ceremony. The architrave of the main door must be decorated using a mixture of rice flour and water. A nirapara (a fully filled para) and a nilavilakku (a lighted lamp) should also be present. Do not forget to place a plantain bunch and some kurutholas (decorations out of palm leaves). At the auspicious time prescribed by the astrologer, the eldest female member of the house followed by other relatives, should circle the house. When entering the house, make sure you place your right foot first and also that you are facing the east direction. Say a prayer to the gods when doing this. The lamp should also be facing the east when the prayers are said to Lord Vishnu, Ganapati, Bhagavati and Paradevathas (family god).
The fire from the homa should be taken and placed in the kitchen fireplace. Use this fire for the housewarming (Palukaachal – boiling milk for the first time). If you do not have a traditional fireplace in the kitchen, the homa kunda can be used for this purpose. The milk boiled thus should be given to everyone present there. The Prasada from the temple should also be given to everyone. Everyone should be made happy before the Griha pravesh. This will lead to a happy family life inside the house.
