Rebirth, often referred to as reincarnation, is the belief that after death, a person's soul or spirit is reborn into a new body. This concept is found in various religions and philosophies, including Hinduism, Buddhism, and Jainism. The cycle of birth, death, and rebirth is known as samsara, and it is influenced by one's actions, or karma, in previous lives. In many traditions, the ultimate goal is to break free from this cycle and achieve a state of enlightenment or liberation, known as moksha in Hinduism or nirvana in Buddhism. Rebirth is often seen as a way for individuals to learn and grow spiritually through multiple lifetimes.
