While the men would learn how to "curl up" in a "sauna-knot" and drink directly from their "clubs", the women would normally ingest their "mahla", female ejaculation, with a straw. According to the Bock Saga this used to be a collective tradition amongst men and women, where "heart-friends" (of the same sex) would share each other's liquids as a special favor and sacrament, to enhance their respective fertility and vitalize their neurological energy. The saga claims that within the heathen cultures this recycling of sperm and sap was obligatory at the age of 7, when it was combined with yoga exercises.
