There is one distince candle connection that i use and yes it works without a doubt to invoke the ascended master Saint Brigid (Brigit) into the room. Read this:

St. Brigid built her Abbey in Kildare around 480AD, on a Hill beside a great oak tree. However, we all know that the Irish/Celts believed in a Goddess Brighid long before she became a Saint and this area was sacred to her.

The Priestesses of Brighid kept her flame eternally lit. 19 Priestesses kept vigil and made sure the flame was never extinguished. This continued for centuries.

I was one of the Priestesses who kept the flame at Kildare, so for me If I light a candle St Brigit is immediately in the room and i feel/see her presence. White or GOld candles i like, but she comes in no matter what colour is burning.
