“Whatever form, feelings, perceptions, experiences, or consciousness there is (the five aggregates), these he sees to be without permanence, as suffering, as ill, as a plague, a boil, a sting, a pain, an affliction, as foreign, as otherness, as empty (suññato), as Selfless (anattato). So he turns his mind/will (citta, Non-aggregate) away from these; therein he gathers his mind/will within the realm of Immortality (amataya dhatuya). This is tranquility; this is that which is most excellent!” [MN 1.436]
