A simple candle-flame meditation:
Light a candle in a darkened room.
Move about two feet away from it and sit down, facing the candle flame.
Then begin breathing in and out quietly through your nostrils.
Let your body relax. Let your breath relax.
Just concentrate on the candle flame.
Watch it for several minutes.
Don’t think about anything in particular. Let your thoughts go; let them settle.
Watch the flame. Let your mind go into it.
Suddenly blow out the candle and close your eyes.
See the image that forms on the inside of your eyelids.
Meditate on that light.
