Here is a short meditation that comes handy in every situation that requires focus, calmness and attention. 


Take a deep breath.


Breathing in through the nose,

Breathing out through the mouth.


Breathing in feeling the lungs expanding,

Breathing out feeling a sense of letting go.


Breathing in to feel the body getting fuller,

Breathing out to feel the release of any tension.


Breathing in feeling alive and awake,

Breathing out feeling muscles relaxing.


Breathing in that sense of fullness,

Breathing out that unnecessary tension.
