cause and effect

What did Leibniz mean by this?
It is true that the Form or the Soul has this advantage over matter, that it is the source of action, having within itself the principle of motion or of change, in a word, το αυτοκινητον, as Plato calls it; whereas matter is simply passive, and has need of being impelled to act, agitur, ut agat.
If only souls are the source of action, would that mean that one body striking another body doesn't really set it in motion (i.e. isn't really the source, or efficient cause, of it's motion)?
Is he suggesting that all moving objects have souls that are the source of the motion?

For Leibniz, there are two levels - the mechanical world (kingdom of nature) where cause and effect are determined by mechanical causes. The other level is the kingdom of nature, which is the metaphysical level of forces and monads. On this, read Specimen dynamicum (for example in Garber & Ariew, Philosophical essays).
