There's a lot of power in the lighting of a candle.
That's probably my biggest grief ritual. On days where I miss him especially hard, or days where I just want a little visual reminder that he's close, I light his candle.
I brought it with me when we travelled at Christmas. Lit it by the tree on Christmas morning as we opened gifts. I even brought it to the hospital when Brayden was born. We couldn't light it, but at that point, it was more what it represented: that Ryan was there with us. And the visual reminder got me through some of the challenging emotions I felt in those first few hours and days.
The candle has also been a bit of a signal (I think). A way of letting Rich know when I'm having a tougher day. Morning, afternoon, evening... When the candle is lit, my heart is a little bit heavier than usual. It's usually good for getting me an extra tight hug, or an especially attentive "How are you today?"
And sometimes, as a ritual of grief, it's just a bit of a habit. I'm always feeling it, and at some point in the last year, lighting the candle has become one more way for me to show it.
