I have seen murti sthapana puja for common festivals like Ganapati. Do we need to do Murti Sthapana for all the Gods we have in our home-temple? Is it like we don't need to do Sthapana for photo-frame in the temple? If we wish to bring in new Idol in our home-temple, is there anything specific we need to do? Like sthapana or anything else? Can someone explain me the importance, conditions and requirements of such puja?
