What is mediation?

"Quest of thee...
...thy run not!searching centre in sphere's surface...
..for it lies within.."

Mediation is not only focus ones energy but also beyond...what happens next...its more like looking into a key hole....as everything as two parts..one part is focus and another is divergence[giving back...spreading energy in other words]..

....manifestation of second part is hard...

More on this ...coming..
