You know, in esoteric traditions there is a belief that we have multiple layers to us: that beyond physical body there is an emotional layer, mental layer Etc. So when the physical body dies others begin to dissolve in certain order. You're probably familiar with post mortem celebration dates when family members get together on 9, 40 days, etc again. But there is one layer, a footprint of sort, that only dissolves if no one remembers you ever again.
I figured it could be my thirties talking but lately I've been thinking about what the heck my footprint is and it's quite motivational.
