"Suffumigacions plurimas facias, perfecte credas, ieiunabis sepe, multas fundas oracions, loca operibus digna elige, aspectus planetarum aspice. He autem operum magice sunt radice."
"Plentiful suffumigations, complete confidence, frequent fasting, many prayers, picking a worthy place for the work, considering the aspects of the planets. These are the root of magical operations."
Picatrix Book IV, Chapter 4, page 191, Aphorism 8 (Translation by Christopher Warnock, Esq.)
