Little thoughts, subtle thoughts,
when followed, stir up the heart.
Not comprehending the thoughts of the heart,
one runs here and there,
the mind out of control.
But comprehending the thoughts of the heart,
one who is ardent, mindful, restrains them.
When followed, they stir up the heart;
one awakened lets them go without trace.
—Buddha Shakyamuni, Discourse to Meghiya
