Ex-witch Beth, who herself has a handful of tattoos, says one cannot ignore the similarities to occult blood rituals.
"A blood ritual is a satanic ritual that is done as a covenant or pact. There are at least two people involved in this type of ritual. The person who is shedding their own blood, and the person who is invoking a demon and its power," Beth writes on her blog, The Other Side of Darkness.
"The person who is shedding their blood is the recipient in this transaction. They are giving their blood (life) in order to receive some sort of benefit, such as life, prosperity, fame, fortune or power. The cuts are now an open doorway for the entrance of evil spirits (demons) (that) you have granted permission. By agreeing to and participating in the shedding of your blood, you have (given) the devil a right to you. Often people who participate in a blood ritual also give over rights to future generations," she continues.
