The Pale Horse is the Card of Fear, especially physical fear.
Get your feet back down on the ground and stabilize. I'll not let fear rule me is your mantra.
The candle is the symbol of wisdom. Find that wisdom today.
"It is better to light one candle then curse the darkness" is a very slight on the less common "Chinese proverb" "'Don't curse the darkness - light a candle." The advice given is "if something is wrong, do something about it rather than complain."
Candle light also creates a warm environment.
You are loved and blessed.
