The Baháʼí writings state that human beings have a "rational soul", and that this provides the species with a unique capacity to recognize God's station and humanity's relationship with its creator. Every human is seen to have a duty to recognize God through His messengers, and to conform to their teachings. Through recognition and obedience, service to humanity and regular prayer and spiritual practice, the Baháʼí writings state that the soul becomes closer to God, the spiritual ideal in Baháʼí belief. When a human dies, the soul passes into the next world, where its spiritual development in the physical world becomes a basis for judgment and advancement in the spiritual world. Baháʼís' believe in the eternal life of the soul rather than reincarnation. Heaven and Hell are taught to be spiritual states of nearness or distance from God that describe relationships in this world and the next, and not physical places of reward and punishment achieved after death.
