Alberto Caeiro said this quote
“ I’m a keeper of flocks.The flock is my thoughtsAnd my thoughts are all sensations.I think with my eyes and with my earsAnd with my hands and feetAnd with my nose and mouth.Thinking about a flower is seeing and smelling itAnd eating a piece of fruit is knowing its meaning.That’s why when on a hot dayI feel sad from liking it so much,And I throw myself lengthwise on the grassAnd shut my hot eyes,And feeling my whole body lying on reality,I know the truth and I’m happy. ”
