Ambapālisutta untranslated

Ambapālisutta 01. Preached at Ambapālivana. The four satipaṭṭhānā form the sole way that leads to the purification of beings, and to the realisation of Nibbāna, etc. SN.v.140.

Ambapālisutta 02. A conversation between Anuruddha and Sāriputta in Ambapālivana. Sāriputta asks the reason of Anuruddha’s serenity and beauty of complexion. It is due to the practice of the four satipaṭṭhānā, says Anuruddha; he himself spends all his time in the practice of them, and so generally do all Arahants. SN.v.301.
