What am I doing?

For the past few years ive been adding the ashes of my incense that I burn into a whisky bottle as well as random salts, juniper berries, among other things I cant remember. All I know is that it feels good to add them to it. I recently moved in the past year and have not been able to add to it due to a sensitive smoke alarm in my new apartment. I'd also like to know what kind of ritual I am doing. The bottle is half full too I'd like it to be full.
