"After that, take clay from the ground, knead it well and form from it a vessel, wide at the top and narrow at the bottom, like the heart within you. Fill this vessel with pure water and put it on the hearth of Jehovah over the sacrificial flame of love. When the water is hot and begins to boil, throw first the white berries into the boiling water. After a short while do the same with the seven red berries. When you see that an the berries have become tender, remove the vessel from the fire, take out with your right hand the soft berries in the same order as they had been put in, place them into your left hand, let them cool down and eat them after the stated order. Then take the vessel with the water in which the berries of the sword have been cooked, pour it onto the hearth of Jehovah and hand the empty vessel to the father of your body. – The Household of God, Book 1, Chapter 16, Paragraph 9
