The practice of satipaṭṭhāna counteracts the tendency to confuse the ego with the body, feelings, mind and mental concepts by disclosing just ‘the body in the body, feelings in feelings, mind in mind, and mental concepts in mental concepts’. Consequently, traits of the ego's behaviour resulting from this confusion, such as discontent (domanassa), dissolve away. They are replaced by a correct comprehension (jñāṇa) and recollection (paṭissati) of the way things are.
