During the pradhoSham(1) time soma sUtra pradaxiNam is the suggested way of circumambulating the God. In some of the temples this is followed always. A point to note here is that the gomukhi is never crossed. gomukhi is the place where the water after anointing (abhiSheka tIrtam) would be flowing northwards out. By doing this way of pradaxiNam one does not step over this holy water.
As per the above marked symbols this pradaxiNam is to be done. First saluting the R^iShabha devar (Holy Bull) go anti-clockwise and salute chaNdIshar (not crossing the gomukhi). Now return in the clockwise manner salute R^iShabham and continue clockwise till the gomukhi (not cross it again). Then return in anti-clockwise direction salute the R^iShabham again and proceed towards chaNdIshar. From there return back clockwise without worshiping R^iShabham and reach the gomukhi. Finally return back anti-clockwise from there to salute R^iShabham and continue to chaNdIshar and return back to R^iShabham and worship the shiva li.ngam (at the altar) by viewing through the space between the two horns of the Holy bull. This is one pradaxiNam. Three such times pradaxiNam to be done.
If you carefully observe the curve traced by doing the pradaxiNam is very similar to the periphery of the crescent. Hence this way of circumambulating is called soma sUtra pradaxiNam.
