suppose there is a vector field V on a manifold M
V generates a flow on M
suppose \gamma(t) is an integral curce in this flow
now there is another vector field W on M
why not define the lie derivative of W with respect to V as the limit of the divide
(W(\gamma+\delta \gamma)-W(\gamma))/\delta \gamma
here the difference is taken by components
i think this is very natural from our experience in the calculus course in undergraduate.
why we need to drag?
