An 1883 interview with renown Kabbalist Dr. Seth
Pancoast,
in which he advises the best wood to make magic wands
"... the divining rod must not be confounded with the
magic wand of the Kabbalah. The two are entirely
different. The magic wand is used for controlling
intelligences as a hand of authority. It controls this
intelligence. Thus, I will intelligently a desire (sic).
That desire never dies until it is fulfilled, or until
it meets a counter desire. In willing this desire the
wand is used, and is of vast power. The distinction
between the diving rod and the wand is that the former
controls energies or physical substances, while the
latter rules over intelligence or spirits."
"What makes the best rod?" "The slender branches of the
hazel tree, or as it is sometimes called witch
hazelwood. There is something singular about the
hazelwood in its power of transmitting what we call
subjective energy. It has this power more than any other
wood. The oak is the next best, though in other
countries, notably in Europe, the wood of the rowan tree
is greatly used. The hazel tree surpasses all, however,
just as certain metals are better than others as
conductors of electricity, copper, for instance, being
one of the best. So is the wood of the hazel tree the
best to convey subjective energy."
