Renunciation
Renunciation is the act of renouncing or rejecting something, especially if it is something that the renouncer has previously enjoyed or endorsed.
In religion, renunciation often indicates an abandonment of pursuit of material comforts, in the interests of achieving spiritual enlightenment. 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, Bhikshu, Bhikshuni, Shramana.
