sn22.122:1.1 At one time Venerable Sāriputta and Venerable Mahākoṭṭhita were staying near Varanasi in the deer park at Isipatana.
sn22.122:1.2 Then in the late afternoon, Venerable Mahākoṭṭhita came out of retreat, went to Venerable Sāriputta, and said:
sn22.122:1.3 “Reverend Sāriputta, what things should an ethical mendicant rationally apply the mind to?”
sn22.122:1.4 “Reverend Koṭṭhita, an ethical mendicant should rationally apply the mind to the five grasping aggregates as impermanent, as suffering, as diseased, as a boil, as a dart, as gloom, as an affliction, as alien, as breaking apart, as empty, as not-self.
sn22.122:1.5 What five?
sn22.122:1.6 That is, the grasping aggregates of form, feeling, perception, choices, and consciousness.
sn22.122:1.7 An ethical mendicant should rationally apply the mind to these five grasping aggregates as impermanent, as suffering, as diseased, as a boil, as a dart, as gloom, as an affliction, as alien, as breaking apart, as empty, as not-self.
sn22.122:1.8 It’s possible that an ethical mendicant who rationally applies the mind to the five grasping aggregates will realize the fruit of stream-entry.”
