" I’m a keeper of flocks.
The flock is my thoughts
And my thoughts are all sensations.
I think with my eyes and with my ears
And with my hands and feet
And with my nose and mouth.

Thinking about a flower is seeing and smelling it
And eating a piece of fruit is knowing its meaning.

That’s why when on a hot day
I feel sad from liking it so much,
And I throw myself lengthwise on the grass
And shut my hot eyes,
And feeling my whole body lying on reality,
I know the truth and I’m happy. "

― Fernando Pessoa , The Keeper of Sheep
