Among some individuals, poverty is considered a necessary or desirable condition, which must be embraced to reach certain spiritual, moral, or intellectual states. Poverty is often understood to be an essential element of renunciation in religions such as Buddhism, Hinduism (only for monks, not for lay persons) and Jainism, whilst in Roman Catholicism it is one of the evangelical counsels. The main aim of giving up things of the materialistic world is to withdraw oneself from sensual pleasures (as they are considered illusionary and only temporary in some religions – such as the concept of dunya in Islam). This self-invited poverty (or giving up pleasures) is different from the one caused by economic imbalance.
