Concentration

Concentration is the act of mental focusing,
or bringing to a single point of centre.

Concentration signifies the state of being at a centre (con and centrum).
Applied to thought, it is the act of bringing the mind to a single point.

Mental force operates best when it is concentrated.

Learn how to place your mind on a particular subject
and inhibit or "shut off" all other thoughts.

The mind can think of but one thing at a time,
and if you concentrate upon a bright thing,
the other thing will fade away.

In perfect concentration time vanishes.

When you have some mental work to do
concentrate on it to the exclusion of everything else,
and you will find that the mind will get right down to business -
to the work at hand -
and matters will be cleared up in no time.
