As a seance tends to require a group of people here is a way an individual can try and commune with the spirits
Find a place you can go to be alone and undisturbed. Light three purple candles and one black cat candle figure. Arrange them on a table with a mirror and turn out all other lights.
As you sit before the mirror and in the candlelight, call out the name of the one you wish to contact. Chant it over and over like a mantra, in time you will see the spectre of the departed behind you in the mirror. Continue to chant thier name and you will hear thier voice as if it were your own thoughts.
When the spirit has said all it wishes the spectre will disappear. Afterwords extinguish the candles and thank you spirit aloud for heading your call. If possible take flowers to the resting place of the departed as a gesture of gratitude.
