Retreat

“Mendicants, meditate in retreat. A mendicant in retreat truly understands. What do they truly understand? They truly understand: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’. Meditate in retreat. A mendicant in retreat truly understands.

Tasmātiha, bhikkhave, ‘idaṁ dukkhan’ti yogo karaṇīyo, ‘ayaṁ dukkhasamudayo’ti yogo karaṇīyo, ‘ayaṁ dukkhanirodho’ti yogo karaṇīyo, ‘ayaṁ dukkhanirodhagāminī paṭipadā’ti yogo karaṇīyo”ti.

That’s why you should practice meditation to understand: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’.”
