The Banyan

From Lenka:

Today I was telling Avi about the Banyan tree in Lahaina: first, a banyan spreads its branch like this (I extend my arm horizontally), then roots go down from the branch until they touch the ground (indicate downward movement with my hand), then a new trunk grows there, a new branch extends horizontally, and so on.

Abi, upon contemplating this: It's like a needle with a thread, as if a banyan tree sews on the ground.
