You need Shiva Lingam if you are a yoga person, or even if you are not. Put the Shiva Lingam wherever you seek enlightenment, while you are concentrating on your breathing, where you are chanting, on your meditation cushion.  Use the Shiva Lingam when your ego has you feeling too small or totally supersized. When it seems like you are sucking life force through a swizzle stick instead of a baba straw. Go “all in” on your essence.
