In this episode Rev. Mikey Noechel offers instructions on mindfulness of breathing as it appears in the Satipatthana Sutta: 

"Herein, monks, a monk, having gone to the forest, to the foot of a tree or to an empty place, sits down with his legs crossed, keeps his body erect and his mindfulness alert.

"Experiencing the whole (breath-) body, I shall breathe in," thus he trains himself. "Experiencing the whole (breath-) body, I shall breathe out," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe in," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe out," thus he trains himself.

Just as a skillful turner or turner's apprentice, making a long turn, knows, "I am making a long turn," or making a short turn, knows, "I am making a short turn," just so the monk, breathing in a long breath, knows, "I am breathing in a long breath"; breathing out a long breath, he knows, "I am breathing out a long breath"; breathing in a short breath, he knows, "I am breathing in a short breath"; breathing out a short breath, he knows, "I am breathing out a short breath." "Experiencing the whole (breath-) body, I shall breathe in," thus he trains himself. "Experiencing the whole (breath-) body, I shall breathe out," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe in," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe out," thus he trains himself."
