In Buddhism, a mental fetter, chain or bond (Pāli: samyojana, saŋyojana, saññojana) shackles a sentient being to saṃsāra, the cycle of lives with dukkha. By cutting through all fetters, one attains nibbāna (Pali; Skt.: nirvāṇa).
Throughout the Pali canon, the word "fetter" is used to describe an intrapsychic phenomenon that ties one to suffering. For instance, in the Khuddaka Nikaya's Itivuttaka 1.15, the Buddha states:
Elsewhere, the suffering caused by a fetter is implied as in this more technical discourse from SN 35.232, where Ven. Sariputta converses with Ven. Kotthita:
