In Vodun, your "spirit" sinks into the ground with your body, then eventually into the water. Eventually, as people forget who you were, your great deeds (the time you payed your grandmothers rent, the time you won that game of soccer with a spectacular kick) attach themselves to the archetypes represented by the Loa, which are the Gods, but also the driving forces of our personality and culture.
As people drink from the water of the earth, they drink your spirit, nameless and shapeless, that carries on your memory. The next time someone does something "great", they carry with them your spirit and the deeds you attributed to the Loa, which ultimately make them even better.
Its an interesting take on culture that works whether you buy into it literally or not.
