Mention blood and many people squirm with discomfort and yet we all have around 8 pints of it fuelling our systems. It is our literal essence and the blueprint of our ancestry. Some people are squeamish about it, some indifferent to it and a lesser minority are actually drawn to it for a variety of reasons. Blood mysteries open the door to taboos of all sorts and some might be disturbing. We will travel from lunar links with women’s mysteries to tribal tattooing and hunting rituals to the practices of live sacrifices.
