When we go to a new place where we will be staying for a considerable period, we like to clean it. But physical spaces also have many invisible occult forces and formations in the atmosphere. They too need cleansing.
Griha Pravesh is a way of doing this cleaning of the inner atmosphere of the place. However, such ceremonies are not necessary for doing this. It is enough to quietly meditate with an aspiration to call the Divine Presence and consecrate the house. One can pray for all who would be living here invoking Peace and Light in the atmosphere.
This can be facilitated by using mantras and soul-uplifting music such as the Mother’s or Sunil Da music.
