I'm just curious what all of you do with your offerings once they've been used. I'm guessing that offerings and their uses differ by sect, so I would love to know what they are and what happens to them.
Everything comes from emptiness and dissolves back into emptiness, so it does not matter much what one does with offerings. Some people have elaborate rules, some people don't.
As for me, food (torma) offerings are put in a high clean place (a stump in my back yard actually), water offerings are tossed out the window into plantings in front of my house. Flowers go in the compost heap for next year's garden.
