I love this old, anonymous Buddhist poem. I came across it only once and kept it printed on a piece of paper for years until I finally committed it elsewhere.
Faith is the seed I am sowing,
wisdom is my plow.
Eliminating evil karma from my deeds, words and thoughts
is my weeding.
Assiduity is my cow
who carries heavy burdens securely.
She goes on and never retreats.
She goes on but never feels sad.
I am tilling like this,
I am seeking like this.
Eternal life is the harvest,
and I free myself from all suffering.
