I took this picture in India last September. Varanasi is sprawled with Shiva Lingams. In meditation we call it the “seat of the mind”.
“The non anthropomorphic Lingam form of Shiva is what is held in reverence in temples all over the Indian sub continent. The Lingam is a symbol. It is a symbol of that which is invisible yet omnipresent. It is hence a a visible symbol of the Ultimate Reality which is present in us (and in all objects of creation ).” text from Templenet.
