Three characteristics of existence
three characteristics of existence; trilakṣaṇa tilakkhaṇa three characteristics of existence. Impermanence (anitya) anicca, Suffering (duḥkha) dukkha and non-self (anātma) anattā are The Three Characteristics of Existence.
trilakṣaṇa (Sanskrit; Pāli, tilakkhaṇa). The three characteristics or marks of all conditioned phenomena. They are impermanence (anitya), suffering (duḥkha), and absence of self (anātman). Although separate, they are also interrelated: it is because things are impermanent that they involve suffering, and it is a corollary of their impermanence that they have no enduring self or core. The implications of the three marks are set out in the first two of the Four Noble Truths.
