Neglected
Viraddha Sutta  (SN 47:33)

“Monks, those in whom the four establishings of mindfulness are neglected, in them the noble eightfold1 path leading to the right ending of suffering & stress is neglected. Those in whom the four establishings of mindfulness are aroused, in them the noble eightfold path leading to the right ending of suffering & stress is aroused.

“Which four? There is the case where a monk remains focused on the body in & of itself—ardent, alert, & mindful—subduing greed & distress with reference to the world. He remains focused on feelings in & of themselves… mind in & of itself… mental qualities in & of themselves—ardent, alert, & mindful—subduing greed & distress with reference to the world.

“Those in whom these four establishings of mindfulness are neglected, in them the noble eigthfold path leading to the right ending of suffering & stress is neglected. Those in whom these four establishings of mindfulness are aroused, in them the noble eightfold path leading to the right ending of suffering & stress is aroused.”

Note

1. The word “eightfold (aṭṭhaṅgiko)” appears in the Thai version of this sutta, but in none of the others.
