For those interested in communicating with dragons 
.
Here is a temple/shrine dedicated to a dragon I visited in Japan.
The bell is to announce the presence of a human and summon it. You light a candle 
as an offering and give money ( like a Catholic Church to a saint).
Most shrines and temples in Japan put their request on a piece of wood that is written by the petitioner and then burnt by the priest.
There is always a ritual water cleansing if the hands and mouth in a water basin prior to all petitions.
Notice the altar set up .
I wonder if I could ask it to show itself to me by petitioning it from these pictures! 
it could be fun if it shows up!
it’s their choice to show up! Am not summoning them am! simply asking nicely!
just for the fun of it or just to see if it works. These are extremely powerful beings.
thanks for the warning!
