What is the correct orientation of a domestic Shiv Lingam? Where the Yoni should face? Any position is formally allowed or should be positioned for example facing North or South? In this case , can someone document the answer with references?
In India, the yoni should be facing North. Also, this can depend on many situations like the region of India. One example is that in Rameswaram, the Lingam is facing north, according to this website. Also the lingam in Ekambareshwarar faces North. I have checked the directions and everything, and can say with certainity that the lingam faces North.
