Some people believe in rebirth. 

In Buddhism, rebirth is a very important idea. It is the belief that life continues after death. This happens in an endless cycle called samsara. 
Many people think this cycle can be painful. They call this feeling dukkha. To stop the cycle, one must reach nirvana. Nirvana is a state of peace. It happens when a person lets go of craving.
What you do affects your next life. This is called karma. Good or skillful karma leads to good realms. Bad or unskillful karma can lead to harder realms. There are six realms where a being can be reborn. These include realms of gods, humans, and animals. 
Different groups have different ideas about rebirth. Some say consciousness moves from one body to another. They compare it to a spark jumping from a hot iron. Others believe there is a middle state called bardo. This state can last for 49 days. Buddhism teaches there is no permanent soul. Instead, rebirth is a way of becoming again.
Rebirth is a central teaching in Buddhism. It is the idea that life continues in a cycle after death. This endless cycle is called samsara. Many people find this cycle to be unsatisfactory or even painful. They use the word dukkha to describe this feeling. The goal for many Buddhists is to stop this cycle. They seek to reach a state of peace called nirvana. This happens when a person lets go of craving. 
How does this cycle work? It is guided by a concept called karma. Karma is the idea that actions have consequences. Good or skillful actions lead to rebirth in good realms. Bad or unskillful actions can lead to rebirth in harder realms. There are six different realms in this cycle. These include the realms of gods, demi-gods, and humans. There are also the animal, ghost, and hell realms. 
This idea has a long history in India. Before the Buddha, some texts like the Vedas mentioned an afterlife. Later texts like the Upanishads discussed reincarnation and karma. The Buddha accepted these ideas but added his own views. He taught that there is no permanent soul or self. This idea is called anattā. This is different from other traditions like Jainism. He also taught that all things change and eventually fall apart.
Different Buddhist traditions have many specific beliefs. Some say consciousness moves from one body to another. They compare this to a spark jumping from a hot iron. Other traditions, like Tibetan Buddhism, believe in an interim state. This middle state is called a bardo. It may last for as long as 49 days. This belief leads to special rituals after someone dies. Some groups even say rebirth happens immediately after death.
Scholars and practitioners use many terms for this process. There is no single exact word for rebirth in Sanskrit or Pali. Instead, they use terms like "re-becoming" or "becoming again." This shows that life is a continuous process. The Buddha reportedly could remember his past lives. He could recall many lives going back ninety-one eons. These memories are linked to deep meditation. 
Rebirth is a foundational doctrine in Buddhism. It describes a cycle where the actions of a sentient being lead to a new existence after death. This endless cycle is known as saṃsāra. Many Buddhists view this cycle as dukkha, which means it is unsatisfactory or painful. The ultimate goal is to achieve Nirvana, or liberation. This state is reached by gaining insight and extinguishing craving. 
The mechanism of rebirth is driven by the law of karma. Karma refers to the ethical consequences of one's actions. Good or skillful actions, called kusala karma, lead to rebirth in favorable realms. Bad or unskillful actions, called akusala karma, result in rebirth in difficult realms. This process is closely tied to the doctrine of Dependent Origination. One of the twelve links in this system is birth, or jāti. This link involves the descent into the womb and the manifestation of the aggregates.
Buddhist cosmology describes six distinct realms within saṃsāra. A being may be reborn into the realm of gods or demi-gods. They may also enter the human realm or the animal realm. There are also the ghost realm and the hell realms. 
There are many different views on what exactly undergoes rebirth. This is a major subject of scholarly study. Buddhism teaches the doctrine of anattā, or not-self. This means there is no permanent soul or unchanging entity. This idea distinguishes Buddhism from other Indian traditions like Jainism. Some traditions believe consciousness, or viññana, acts as a continuous stream called a santana. They compare the movement of consciousness to a spark jumping from a hot iron. 
History shows that these ideas evolved over time in India. Early Vedic literature focused on ancestor worship and rites like sraddha. Later Vedic texts, such as the Upanisads, introduced concepts of reincarnation. The Buddha accepted some of these premises but introduced unique innovations. He taught that all compounded things are subject to dissolution, known as anicca. He also asserted that there is no soul tying the cycle of rebirths together. This was a significant departure from the Sramana schools that affirmed the existence of a soul.
Different traditions also disagree on the timing of rebirth. The Theravada tradition often asserts that rebirth occurs immediately. They suggest that no physical thing moves between lives, only a causal link. In contrast, Tibetan Buddhism posits an interim existence called a bardo. This state between death and rebirth may last as long as 49 days. This belief is a central part of Tibetan funerary rituals.
Language also reflects the complexity of these ideas. There is no single English word that perfectly matches the Sanskrit or Pāli terms. Instead, terms like punarbhava mean "re-becoming" or "becoming again." This emphasizes that existence is a continuous process rather than a soul moving. The Buddha is said to have possessed knowledge of his own past lives. He reportedly could recall lives stretching back as far as ninety-one eons. Such memories are often associated with deep meditative states, or samadhi.
Rebirth remains a central theme in Buddhist thought and practice. It connects ethics, cosmology, and the nature of the mind. The study of rebirth helps explain how karma and causality function. It also provides the motivation for seeking Nirvana. By understanding the links of Dependent Origination, practitioners seek to break the cycle. This journey from suffering to liberation is the core of the Buddhist path.
