It can't be named...

Its been quite some time since these lines crept into my mind.

How does one attain it?
One, which can't be disturbed by
Chaos,
Nor which requires Silence to
sustain...
A state when You are
Neither happy nor sad...
When Nothing can make a
difference to your Being,
And yet - Everything matters.
The search begins when you start
chasing it,
And terminates when it finally
Finds You.
And then it is attained, felt, unkept, lost.
It can't be named, this feeling.
It must be felt once -
And then through it,
We find Ourselves.
