"A virtuous monk, Kotthita my friend, should attend in an appropriate way to the five clinging-aggregates as inconstant, stressful, a disease, a cancer, an arrow, painful, an affliction, alien, a dissolution, an emptiness, not-self. Which five? Form as a clinging-aggregate, feeling... perception... fabrications... consciousness as a clinging-aggregate. A virtuous monk should attend in an appropriate way to these five clinging-aggregates as inconstant, stressful, a disease, a cancer, an arrow, painful, an affliction, alien, a dissolution, an emptiness, not-self. For it is possible that a virtuous monk, attending in an appropriate way to these five clinging-aggregates as inconstant... not-self, would realize the fruit of stream-entry."

Although, for an arahant, there is nothing further to do, and nothing to add to what has been done, still these things -- when developed & pursued -- lead both to a pleasant abiding in the here-&-now and to mindfulness & alertness."
