2 Tablespoons of Ground Holly (for Spirit Calling)
A pinch of Cypress (for Longevity)

WHAT TO DO:
Let the herbs be prepared while the name of the loved one is repeated by the preparer. 
Place the herbs in the Silver Bowl.
Lay in the treasure of the loved one, should one be available.

Prick your left finger, this way the blood flows straight from the heart.
Add the blood to the bowl while calling out the name of loved one. After say:

Nos te voco"

The loved one should be summoned in full wholeness and freshness of life.
