The three girdles of such fure-pit should be with the measure of 4, 3 and 2 angulas. If only one girdle
is to be provided, it should be with a measure of 6 angulas. In the middle of the upper girdle, a yoni-structure
should be designed so as to be in the shape of the elephant-lip, with a measure of 12 angulas. There should
be neck-like structure above the top level of empty space of the pit, with a measure of one angula. If such
fire-pit has not been constructed, the Guru may design a sthandila(a raised square platform) and create the
Sivagni there, after performing the concerned sacramental rituals. In a fire-pit for which the concerned
sacramental rituals are not performed, the Sivagni would never manifest. And in the fire-pit in which the
Sivagni has not been duly enabled to manifest, all the oblations offered there would not yield the intended
fruits.
