What is purgatory meaning?

Purgatory is a concept in some Christian denominations, particularly in the Roman Catholic Church. It is believed to be a state or condition of purification, in which the souls of the faithful departed undergo a process of cleansing before they can enter heaven. The duration of purgatory is not specified in the Catholic Church, although it is believed to be finite. The idea of purgatory is based on the belief that while a person may die in a state of grace, they may still have unrepented sin or temporal punishment for their sins. The cleansing process is said to involve purification by fire, in which the soul is made ready to enter heaven. The concept of purgatory is not universally accepted in Christianity, with some denominations rejecting it entirely.
