We discuss various aspects of the post-Newtonian approximation in general relativity. After presenting the foundation based on the Newtonian limit, we use the (3+1) formalism to formulate the post-Newtonian approximation for the perfect fluid. As an application we show the method for constructing the equilibrium configuration of non-axisymmetric uniformly rotating fluid. We also discuss the gravitational waves including tail from post-Newtonian systems.
