How to play two animations at the same time on the same character

Hi I hope you are having a good day.

I need help playing two animations at same time. On the same armature possible.
I saw a couple of threads that suggested using
Different layers, I also looked at number of blend files but these where all beyond my understanding
May someone please explain the process in simple terms/steps.
Note : I am using blender 2.68a

Thank you Any Solutions and Help will be greatly appreciated
