Wikipedia helps decipher this beautiful tradition which symbolises the passage of the four advent weeks leading up to Christmas. But there's a practical meaning too.
Just sit and listen quietly. Here's the story of the four advent candles, which one dark, cold winter night started to speak:
The first candle sighted and said "My name's Peace, but my light shines ever so timidly as there's little peace". Flickering a last time, it faded into the dark.
With a shy light the second candle said "My name is Faith, but I'm not of much use, as people don't want to know God, so there's little reason for me to shine". And with a faith breeze it went out.
Then the third candle spoke with a sad voice "My name is Love. I no longer have the strength to burn. People put me aside; only care for themselves and not others any longer". And with a final flicker it went out as well.
That's when a small child entered the room. Looking at the 3 candles it started to cry saying "You should be burning..." Here, the fourth candle raised her voice and gently said "Don't be afraid. As long as I burn, we're able to relight them. My name is Hope".
With this, the child rekindled Peace, Faith and Love with the light of Hope.
