The following if from Dancing with Dragons by D.J. Conway
Guardian dragons are the most friendly of the species and the most fun-loving. Then enjoy simple impromptu rituals that include dancing, singing, and general fun. Simple, very relaxed rituals are an excellent was to introduce children into the field of ritual and getting acquainted with dragons. It is also a very good way for adults to unwind and release stress.
These dragons are attracted to ginger and sweet-smelling and spicy incenses. They are greatly interested in divination and have a tendency to hang over your shoulder while you are reading cards or practicing crystal gazing, for instance. They are interested in stories, especially if the dragon in portrayed as powerful wily, and not defeated by puny mottals.
If you are having trouble visualizing your dragons, try using a piece of rock crystal. It does not have to be flawless, nor does it have to have points. It would appear that this type of crystal acts as a kind of magnifying glass to the psychic through the third eye in the middle of the forehead. When you have mastered the technique with rock crystal, experiment with other kinds of translucent rocks.
Remember, dragons have individual tastes in things, just as humans do.
