As many arrows, loosed several ways, come to one mark ... so may a thousand actions, once afoot, end in one purpose.

Our reading
An editorial interpretation.
Arrows fired from different places can all land on one target. Shakespeare uses that picture to say many separate actions can still serve a single purpose. It makes scattered effort sound coordinated, heading toward the same mark.
