A path is a long strip of ground which people walk along to get from one place to another.

Your path is the space ahead of you as you move along.

The path of something is the line which it moves along in a particular direction.

A path that you take is a particular course of action or way of achieving something.

You can say that something is in your path or blocking your path to mean that it is preventing you from doing or achieving what you want.

If you cross someone's path or if your paths cross, you meet them by chance.
