[1253] Thus have I heard. On one occasion the Venerable Anuruddha was dwelling at Sāvatthī, in Jeta's Grove, Anāthapiṇḍika's Park. Then, while the Venerable Anuruddha was alone in seclusion, this reflection arose in his mind: "Those, whoever they may be, who have neglected the four establishments of mindfulness (satipaṭṭhāna) have neglected the noble path (magga) leading rightly to the destruction of suffering (dukkha); those, whoever they may be, who have undertaken the four establishments of mindfulness have undertaken the noble path leading rightly to the destruction of suffering."
