As a Master Gardener, i am now working for my Master Composter certification. I take every opportunity to educate people about the ins and outs of compost: what goes in--the greens (i.e., nitrogen) and the browns (i.e., carbon) and what stays out--wood ash, meat scraps, dairy, and fats.
As part of my Master's degree in Counseling, i attended a workshop on Post Traumatic Stress Disorder presented by a social worker who was a Holocaust survivor. She brought in a jar of compost from her pile that contained scraps of old clothes, a chicken bone, and a rusty nail.
All of our experience is composted and becomes the soil into which we plant our subjective view of the next moment. Then that moment becomes the soil out of which the next moment springs.
A good reason to sweeten the present moment with kindness and compassion.
