Response from my wife...

Interesting to consider origins of words: 

Old Norse raptr ‘rafter,’ late Middle English (in the sense ‘beam, rafter’): The verb dates from the late 17th century.

Prior to 19th century Raff (perhaps Scandanavian dialect)= abundance;

In English became "raft"=floating mass

So, how do we get from a single entity, solid and supportive

To Abundance

And then become a floating mass??

I think perhaps all of existence is a floating mass, everything-that-is

In relationship (to other humans, other entities, sentient beings, objects, time), there are endless possibilities: abundance!

Each of us, a single raft is a solid and supportive beam of existence, supporting all the rest...

Indra's net, perhaps?
