The act of spirit cooking involves Abramović using pigs blood as a way of connecting with the spiritual world, to cook up thoughts rather than food. A video of the practice shows her writing various statements with the blood, such as with a sharp knife cut deeply into your middle finger eat the pain.
Abramović is known, and lauded, for work that focuses on pain, blood and the relationship between the performer and the audience. Her work has won many awards, including the Golden Lion at Venice.
