Many Hindus believe that the way to achieve nirvana—a state of complete spiritual perfection—is to lead a severe ascetic lifestyle of material and physical self-denial, devoting life to a spiritual rather than material quest.
Nirvana is a place of perfect peace and happiness, like heaven. In Hinduism and Buddhism, nirvana is the highest state that someone can attain, a state of enlightenment, meaning a person's desires and suffering go away.
