I used to tend the flame with a cill that I began with two of my dear sisters. As I look back now, it was a matter of going through the motions for me.
I was on the starting path, and I had heard of Brighid's Flame and cills and such and thought it would be 'cool', I suppose, but I didn't get much out of it beyond that.
That was before a very... difficult time in my life. I, quite literally, lost my way... While it was something of a 'deep, dark night' for me... submerged into the Cauldron... it could have also been Brighid's Flame of transformation. I came out of it knowing better what's truly important. Not just in a mental capacity, but in my heart's capacity. Things have taken on more meaning. I've approached things less in a superficial manner and more in a meaningful one... It's difficult for me to explain... I shed the 'unnecessary'... things that are simply there 'for show' - appearances - to get down to the heart of matters.
So, I suppose it is for that reason that I wish to tend the flame... Not only to thank the Lady for having shown me the way, but hoping that she'll assist me in making more meaningful transformations in my life, for I am not so naive to believe that I'm done. There is still much work to be done. :-)
