Renunciation (or renouncing) is the act of rejecting something, especially if it is something that the renunciant has previously enjoyed or endorsed.
In religion, renunciation often indicates an abandonment of pursuit of material comforts, in the interests of achieving spiritual enlightenment. It is highly practiced in Jainism. In Hinduism, the renounced order of life is sannyāsa; in Buddhism, the Pali word for "renunciation" is nekkhamma, conveying more specifically "giving up the world and leading a holy life" or "freedom from lust, craving and desires". See Sangha, Bhikkhu, Bhikkhuni, Śramaṇa. In Christianity, some denominations have a tradition of renunciation of the Devil.
Renunciation of citizenship is the formal process by which a person voluntarily relinquishes the status of citizen of a specific country. A person can also renounce property, as when a person submits a disclaimer of interest in property that has been left to them in a will.
